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 2.6 inches. A baseball analyst wonders whether the standard deviation of heights of major-league basebal players is less than 2.6 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= 0.01 level of significance. What are the correct hypotheses for this test? The null hypothesis is Ho 2.6. The alternative hypothesis is H 2.6.

B. Calculate the value of the test statistic.
χ2=____
C. Use technology to determine the P-value for the test statistic.
The P-value is___
D. What is the correct conclusion at the α=0.01 level of significance?
Since the P-value is (greater/less) than the level of significance, (reject/ do not reject) the null hypothesis. There (is/ is not) sufficient evidence to conclude that the standard deviation of heights of major-league baseball players is less than 2.6 inches at the inches at the 0.01 level of significance.
