A weight loss program claims that program participants have a mean weight loss of at least 10 pounds after 1 month. You work for a medical association and are asked to test this claim. A random sample of 30 program participants and their weight losses (in pounds) after 1 month is listed in the table below. Assume the population standard deviation is 33. At α=0.02, do you have enough evidence to reject the program's claim? 5.4 6.1 6.6 6.8 7.4...

Problem #6: The weight of a sophisticated running shoe is normally distributed with a mean of 14 ounces. (a) What must the standard deviation of weight be in order for the company to state that 95% of its shoes weight less than 15 ounces? (b) Suppose that the standard deviation is actually 0.83. If we sample 8 such running shoes, find the probability that exactly 4 of those shoes weigh more than 15 ounces. Problem #6(a): Round your answer to...
