A neighbor grows and sells cucumbers in the summer. She packages them in plastic storage bags and claims that the true mean weight of these bags is 1 pound. To test her claim, you take a random sample of 64 of these cucumber-filled bags, weigh them, and find the sample mean weight to be x = 1.03 pounds. The population standard deviation is o = 0.08 lbs. (a) Using Minitab determine the 90% confidence interval for the true mean weight u cucumber bags using the sample data. (b) With 90% confidence, is the neighbor's claim true? Why or why not?
