- the distribution of sample means consists of thearrow_forwardwhen you have means from two different samples, it is best to conduct a what test?arrow_forwardA college football coach was interested in whether the college's strength development class increased his players' maximum lift (in pounds) on the bench press exercise. He asked four of his players to participate in a study. The amount of weight they could each lift was recorded before they took the strength development class. After completing the class, the amount of weight they could each lift was again measured. What is being tested in this situation and what distribution will be used to conduct the test? Group of answer choices a.Two independent means, normal distribution. b.Single population mean, use the t-distribution. c.Single population mean, use the normal distribution. d.Two independent proportions, use the normal distribution. e.Two independent means, use the Student’s-t distribution.arrow_forward
