Q2. During the COVID-19 pandemic, the demand for personal protective equipment (PPE) masks surged dramatically due to heightened health concerns. However, contrary to the typical behavior predicted by the law of demand, the price of PPE masks also increased despite the high demand.

On the other hand, in certain regions, there were instances where masks were in abundant supply, yet prices remained relatively high due to hoarding and panic buying. Analyze the exceptions to the law of demand and supply observed in this scenario concerning PPE masks. How do these exceptions challenge traditional economic theories, and what factors contribute to this deviation from the standard demand-supply relationship? (10 Marks)

Introduction
Effective leadership is shaped by personality traits that influence how leaders interact with their teams. Geeta, a team leader at BTech Solutions, is known for her high level of organization and attention to detail, but her rigid adherence to schedules creates tension with her team.

Hypothesis testing is a fundamental aspect of statistical analysis in research. It enables researchers to make data-driven decisions by assessing whether an observed effect is statistically significant or simply due to chance. The null hypothesis () represents the default assumption that there is no effect or no significant difference, while the alternative hypothesis () suggests that there is an effect or a deviation from the assumed norm. Understanding these

Introduction
In statistical analysis, correlation and regression are essential tools for understanding relationships between variables. Pearson’s correlation coefficient measures the strength and direction of a linear relationship between two variables, while linear regression provides a predictive equation that describes this relationship. In this section, we calculate the Pearson correlation coefficient and derive the regression equation for given datasets. These analyses help in data-driven decision-making, forecasting, and pattern recognition in various fields
