To estimate the defect rate of a batch of cars, we sample 25 cars out of 400 cars in a batch. In other word. 25 is the sample size and 400 is the population size. 4 of them is defect. Since the population is small we need to make an adjustment. What is the adjusted 95% confidence interval estimation of the defect rate? a. (0.018, 0.302) b. (-0.022, 0.990) c. (0.030, 0.045) d. (0.001, 0.056)

A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.
