#3

Question # 3 Robert is conducting a hypothesis test concerning a population mean. The hypotheses are as follows. Ho:M = 50 H : H > 50 He selects a sample of size 35 and finds that the sample mean is 60. He then does some calculations and finds that for samples of size 35, the standard deviation of the sample means is 3.2. Do you think that he should reject the null hypothesis? Why or why not
