A factory that makes electric motors wants to study if there is any connection between the hours that it spends training its technicians and the number of defective motors that are manufactured. Ten technicians are chosen randomly and their individual training hours is recorded along with the number of defective motors produced. The following table summarizes the findings. 1. [3pts] Find and interpret the slope. 2. [4pts] What is the estimated regression equation? 3. [2pts] What is value of the correlation coefficient? What can you comment on the strength and direction of the relationship between the two variables? 4. [7pts] Use a t test (including all four steps) to determine if the two variables are related. Use the output of your Excel spreadsheet for regression analysis. Show your work. 5. [4pts] Calculate and interpret the 95% confidence interval for the population slope.
