37. I want to know which of two manufacturing methods will be better. I create 10 prototypes using the first process, and 10 using the second. There were 3 defectives in the first batch and 5 in the second. Find a 95% confidence interval for the difference in the proportion of defectives. a. (-0.62, 0.22) b. (-0.56, 0.22) c. (-0.493, 0.160)
