And solve the following question
A sample of 30 students’ test scores is randomly selected from a large class. The sample has a mean score of 85 points and a standard deviation of 6 points. Calculate the 99% and 95% confidence intervals for the population mean. (6 Marks)
(10 Marks)
Ans 1.
Introduction
Estimation is a fundamental aspect of statistics used to draw inferences about population parameters based on sample data. In any study or research where it is impractical to gather information from every member of a population, estimation provides a practical alternative by allowing us to make educated guesses about the population based on a sample. There are two primary types of estimates: point estimates and interval estimates. A point estimate provides a single value as an estimate of a population parameter, while an interval estimate provides a range within which the parameter is expected to fall, offering a degree of confidence in the estimate. The concept of confidence intervals, which is part of interval estimation, allows researchers to estimate population parameters with a specified probability. In this analysis, we will explore

Q2 (A) The monthly rent paid by a group of 15,000 tenants in a city is found to be normally distributed with a mean of ₹12,000 and a standard deviation of ₹1,500. Answer the following questions:
- a) What is the probability that a tenant selected at random pays more than ₹10,500 in rent?
b) What is the probability that a tenant selected at random pays more than ₹14,700 in rent?
(5 Marks)

Introduction
Probability distributions are essential in understanding data patterns, especially in large datasets like monthly rents for tenants. In this case, rent data for 15,000 tenants follows a normal distribution, with a mean of ₹12,000 and a standard deviation of ₹1,500. Understanding how likely a particular rent is can provide insights into expected costs for tenants and property managers. Here, we calculate the probabilities of rents being above certain values using conce
Q2 (B) A pharmaceutical company claims that its new drug reduces the average recovery time from the flu to less than 7 days. Historically, the average recovery time for the flu without the drug is 7 days. To test this claim, the company conducted a study with 50 patients who took the new drug. The sample mean recovery time was 6.5 days with a population standard deviation of 2 days. Can we accept the company’s claim at the 5% level of significance? (5 Marks)
Ans 2B.
Introduction
In hypothesis testing, pharmaceutical companies often use statistical methods to validate claims about new drugs. Here, a company claims that its new drug reduces the average recovery time from the flu to less than 7 days, a significant improvement from the historical average of 7 days. To test this claim, a sample of 50 patients was studied, revealing an average recovery time of 6.5 days. We will use a one-sample Z-test at a 5% significance level to determine if the
Organizational Behavior
Dec 2024 Examination
Q1. Nisha, as a head of operations at a mid-sized manufacturing company, has a team that is diverse in both experience and motivation levels. The company has recently undergone a turnaround process, that has left some employees feeling insecure about their future roles. Nisha observes that some of her team members are highly motivated and consistently exceed their targets. A few others seem disengaged and often struggle to meet their goals.
As an OB expert, Nisha is considering different motivational strategies to improve team performance. She is aware that a one-size-fits-all approach may not work. Based on motivation theories (Maslow’s Hierarchy of Needs, Herzberg’s Two-Factor Theory, and Vroom’s Expectancy Theory), evaluate the possible reasons for the varying levels of motivation in Nisha’s team. Recommend strategies Nisha could implement to boost motivation across the team, considering both intrinsic and extrinsic motivators. (10 Marks)

Introduction
In the modern business environment, motivation plays a crucial role in achieving organizational success. For leaders like Nisha, managing a diverse team with varying levels of experience, skills, and motivation can be challenging, especially after a significant organizational change. Motivation is the driving force that encourages employees to meet their goals and contribute effectively to the organization. However, due to the recent turnaround process, some team members may feel insecure about their roles, which can impact their engagement levels. The disparity in motivation levels within Nisha’s team suggests that a single approach may not suffice.

Micro Economics & Macro Economics
Dec 2024 Examination
Q1: The COVID-19 pandemic of 2020 caused significant disruptions to international business operations because numerous firms relied on suppliers from different nations, notably China. Many companies used lean production methods and kept low inventories in order to cut costs. However, this made them susceptible to supply chain interruptions. For instance, worldwide supply lines for electronics, including parts for laptops and cell phones, were impacted when lockdowns forced Chinese facilities to close. The fact that a large portion of auto parts were made in China presented difficulties for auto makers as well, resulting in major global production halts.
What impact would the COVID-19 worldwide lockdowns have on Europe’s supply curves for consumer electronics and auto factories? Explain your observations about the aforementioned scenario, emphasizing the supply side and the shift in the supply curve.
(Note: You can make assumptions as per the requirement of the case.) (10 Marks)
Ans 1.
Introduction
The COVID-19 pandemic in 2020 created unprecedented disruptions in global supply chains, particularly impacting industries heavily reliant on international suppliers, such as consumer electronics and the automotive sector. Europe, like many other regions, faced severe consequences as a result of lockdowns, especially in China, which is a major supplier of critical components. Lean production strategies, which emphasize minimal inventory to reduce costs, became a double-edged sword, leading to significant vulnerabilities when supply chains were interrupted. As a result, many European firms found themselves unable to source key parts, halting production and affecting availability in the market. This supply shock led to shifts in supply curves, causing both

Q2 (A): The London “black cab” taxis are amongst some of the most expensive in the world. They compete to some extent with minicabs, which tend to be cheaper. However, minicabs are not allowed to pick up customers off the street; they have to be booked in advance, and their drivers do not have to memorize a London street map. Minicabs operate in a more competitive market and require less of the drivers. Black cab (licensed) cab drivers must pass a background check and medical test and pay fees over 200 pounds. This may help to ensure that passengers are safe and drivers are accountable, but it also means that they have a monopoly on picking up people on the streets. Elaborate on the given market structure (Black cabs and Minicabs) and discuss the implications for markets with high barriers to entry. (5 Marks)
Ans 2A.
Introduction
The London taxi market is an illustrative example of a market segmented by regulatory barriers, specifically in the contrast between “black cabs” and “minicabs.” Black cabs, known for their iconic appearance and premium rates, hold exclusive rights to pick up customers off the street, a privilege secured through strict licensing requirements. Minicabs, though cheaper and less regulated, cannot legally pick up street passengers without prior booking. This structure, highlighting the impact of regulatory and economic barriers, provides insights into competitive dynamics and consumer

Q1: Jyoti, a seasoned marketing executive, was tasked with presenting a new product launch strategy to two very different audiences: the company’s senior management team and a group of young, tech-savvy consumers. She knew that a one-size-fits-all approach wouldn’t be effective. She needed to adapt her message and delivery to resonate with each group. What factors must Jyoti keep in mind for controlling the style and tone for each of her audience? (10 Marks)
