What is the formula needed for part a? I would also like help on how to do parts c and e. 1. A manufacturing company is interested in predicting the number of defects that will be produced eachhour on the assembly line. The managers believe that there is a relationship between the defect rate andthe production rate per hour. The managers believe that they can use production rate to predict thenumber of defects. The following data were collected for 8 randomly selected hours.Production rate/h4045203540503050Defects2354a. Use the least-squares method to predict the number of defects when production rate is 55.b. Interpret the meaning of the regression coefficients in this problem.c. Compute the standard error of the estimate.d. At a significance level of .01 can you conclude that production rate is a good predictor ofthe number defects?e. Find a 98% confidence interval estimate number of defects when production rate is 55.
