   62.13 65.09 64.18 66.72 63.09 61.15 67.50 64.65

Answer to Question 1

B

Answer to Question 2

Test statistic: X2 = 9.260. Critical values: X2 = 6.262, 27.488. Fail to reject . There is not sufficient evidence to support the claim that heights of women aged 25 to 34 have a standard deviation different from 2.9 in.
