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 baseball players is less than 2.6 inches. The heights (in inches) of 20 randomly selected players are shown in the table. A. Calculate the value of the test statistic. chi Subscript Superscript 2 equals (Round to three decimal places as needed.) B. Use technology to determine the P-value for the test statistic. The P-value is
