Data show that men between the ages of 20 and 20 in a general population have a mean height of 69.3 inches, with a standard deviation of 2.5 inches. A baseball analyst wonders whether the standard deviation of heights of major-league baseball players is less than 2.5 inches. The heights (in inches) of 20 randomly selected players are shown in the table. E Click the icon to view the data table. Test the notion at the a= 0.05 level of significance. What are the corect hypotheses for this test? The null hypothesis is Ho: | 2.5 The alternative hypothesis is H,: 2.5. Calculate the value of the test statistic. x =Round to three decimal places as needed.) Use technology to determine the P-value for the test statistic. The P-value isO (Round to three decimal places as needed.) What is the correct conclusion at the a= 0.05 level of significance? Since the P-value is V than the level of significance, V the null hypothesis. There V sufficient evidence to conclude that the standard deviation of heights of major-league baseball players is less than 2.5 inches at the 0.05 level of significance.

6979687#/Skip// The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n = 50; = 40.35 pounds; 8 = 2.8 pounds a) Identify the null and alternative hypotheses?
