The Graduate Management Admission Test (GMAT) is a test required for admission into many masters of business administration (MBA) programs. Total scores on the GMAT are normally distributed. The Graduate Management Admission Council, who administers the test, claims that the mean total score is 528. Suppose a random sample of 11 students took the test, and their scores are .given below 490 ,450 ,413,727,663,521 ,550,414,560,699 500 Does the sample evidence suggest the mean total ?score is different from at the level of significance The test statistic value, is (s = 109.6559 Consider) with 11 degrees of freedom to = 0.4922 with 10 degrees of freedom to = 0.4922 z0 = 1.6324 z0 = 0.4922

The U.S. National Center for Health Statistics complies birth statistics and publishes the results in vital statistics of the United States. The Center has historically believed that the mean of all newborns in the U.S. has been no less than 6.95 pounds. A sample of babies is selected so that the center can revise its belief. The following birth weights, in pounds are recorded: 7.4, 6.0, 8.6, 4.5, 2.0, 7.9, 4.0, 2.6, 5.9, 7.3, 7.3, 7.0, 6.3, 8.1, 7.1, 7.3, 6.6, 5.2, 9.8, 8.0, 10.9, 6.5, 3.8, 5.0, 8.0 a). At 5% level of significance, do these data provide sufficient evidence to refute the Center’s belief? Your conclusion must be in terms of the P-Value as well as setting up a Rejection Region. You must show all necessary work. b). Which statistical distribution should be applied in this situation and why? Explain carefully.

Traditional statistics (means, variances, and hypothesis tests) are not used to evaluate the results from a single-case study. Explain how the results are evaluated.
