Data show that men between the ages of 20 and 29 in a general population have a mean height of 69.3 inches, with a standard deviation of 3.1 inches. A baseball analyst wonders whether the standard deviation of heights of major-league baseball players is less than 3.1 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 = 0.10 level of significance. Data table What are the correct hypotheses for this test? The null hypothesis is Hg: V3.1. 72 74 71 72 76 70 77 74 72 72 77 72 75 70 73 74 75 73 74 74 The alternative hypothesis is H,: V3.1. Calculate the value of the test statistic. y2 =O (Round to three decimal places as needed.) Use technology to determine the P-value for the test statistic. Print Done The P-value is N. (Round to three decimal places as needed.) What is the correct conclusion at the a = 0.10 level of significance? Since the P-value is V than the level significance, V the null hypothesis. There sufficient evidence to conclude that the standard deviation of heights of major-league baseball players less than 3.1 inches at the 0.10 level of significance.
