Thirty GPAs from a randomly selected sample of statistics students at a college reported a mean of 3.11 and the standard deviation was 0.36. Assume that the population distribution is approximately Normal. The technician in charge of records claimed that the population mean GPA for the whole college is 2.88. The chair of the mathematics department claims that students typically have higher GPAs than the typical college student. Test this claim. State the null and alternative hypotheses Find the test...

3) Suppose you know the true mean GPA of Howard Community College and are interested in seeing how students in your stats class compare to the college average. Compared to the sampling distribution of the means for small samples (say n = 4), how will the sampling distribution of the means be different for larger samples (say n = 25)? a.) The sampling distribution for n=25 will have a larger mean b.) The sampling distribution for n=25 will have a...
