Solution: Business Statistics Assignment, Hypothesis Testing

This document presents a comprehensive solution to a business statistics assignment. It covers hypothesis testing, including the calculation of t-values and the determination of confidence intervals. The solution addresses two specific problems: the first involves comparing the means of two groups (SBA and engineering students) and calculating a 95% confidence interval. The second problem focuses on testing the difference between the means of two groups at a 1% significance level, calculating a t-statistic, and comparing it to a critical value to determine whether to reject the null hypothesis. The assignment uses formulas and provides a detailed, step-by-step approach to solving the statistical problems, with references to cited works.
