Question 4 1 pts A health care provider claims that the mean overpayment on claims from an insurance company was 0. The insurance company is skeptical, believing that they were overcharged. They want to use sample data to substantiate their belief. A sample (audit) of 40 claims was collected, and a sample mean overpayment of $4 was calculated with a standard deviation of $13. Suppose that we can tolerate a chance of 5% of rejecting the claim when it is true. What is the p-value for the test? 0.0294 0.0589 0.0391 O 0762 0.9706 1 pts Question 5 Pineapple Corporation (PC) maintains that their cans have always contained an average of 12 ounces of fruit. The production group believes that the mean weight has changed. They take a sample of 15 cans and find a sample mean of 12.03 ounces and a sample standard deviation of .06 ounces. What conclusion can we make from the appropriate hypothesis test at the 10 level of significance? Do not reject the null hypothesis and conclude that there is enough evidence to conclude that the mean weight has changed O Reject the null hypothesis and conclude that there is enough evidence to conclude that the mean weight has changed O Do not reject the null hypothesis and conclude that there is not enough evidence to conclude that the mean weight has changed O Reject the null hypothesis and conclude that there is not enough evidence to conclude that the mean weight has changed
