This assignment solution focuses on business decision-making using statistical analysis. The student analyzes survey data from University A, examining GPA distribution, birthday frequency, and child rank to identify patterns and potential biases. Inferential statistics, including z-tests and t-tests, are employed to test hypotheses related to the proportion of rural students and weekly rent comparisons between two suburbs. The solution presents the null and alternative hypotheses, test statistics, p-values, and conclusions drawn from the analysis, providing a comprehensive understanding of statistical techniques applied to business scenarios. The assignment demonstrates the application of hypothesis testing to determine if there is a significant difference in the proportion of rural students and to compare average weekly rent in two different suburbs.
