1. A manufacturing company is interested in predicting the number of defects that will be produced each hour on the assembly line. The managers believe that there is a relationship between the defect rate and the production rate per hour. The managers believe that they can use production rate to predict the number of defects. The following data were collected for 8 randomly selected hours. Production rate/h 40 45 20 35 40 50 30 50 Defects 2 e. At a significance level of .01 can you conclude that production rate is a good predictor of the number defects? f. Find a 98% confidence interval estimate number of defects when production rate is 55. 312 3546
