question 14

Essay

Use the traditional method to test the given hypothesis. Assume that the population is normally_
distributed and that the sample has been randomly selected. Heights of men aged 25 to 34
have a standard deviation of 2.9. Use a 0.05 significance level to test the claim that the heights
of women aged 25 to 34 have a different standard deviation. The heights (in inches)of 16
randomly selected women aged 25 to 34 are listed below. Round the sample standard
deviation to five decimal places. $$\begin{array} { c c c c c c c c } 62.13 & 65.09 & 64.18 & 66.72 & 63.09 & 61.15 & 67.50 & 64.65 \\63.80 & 64.21 & 60.17 & 68.28 & 66.49 & 62.10 & 65.73 & 64.72\end{array}$$
