AI Summary
This report presents a statistical analysis of data from 150 manufacturing industries. The analysis includes descriptive statistics such as means, standard deviations, and ranges for variables like the number of employees, sales percentages, gross revenue, manager salaries, and manager ages. Regression analysis is performed to explore the relationships between these variables, revealing an R-squared value of 0.35, indicating the model's ability to explain the variance in manager's age. The report also includes a one-sample t-test to examine the hypothesis that the mean age of managers is less than or equal to 48 years. The findings suggest that the model is significant, with specific coefficients impacting the dependent variable, and the t-test results support the conclusion that the mean age of managers is indeed approximately 48 years or less, indicating a relatively young management demographic across these industries.
