A researcher was interested in comparing the heights of women in two different countries. Independent simple random samples of 9 women from country B and 9 women from country A yielded the following heights (in inches).
Country B.......... Country A
58.1...................... 56.3
66.4....................... 60.2
61.7....................... 61.7
62.0....................... 61.8
67.3........................ 61.0
64.9........................ 60.6
64.7........................ 60.0
68.0....................... 61.4
68.6 .......................59.0
At 10% significance level do the data provide sufficient evidence to conclude that the mean height of
women in country B is greater than the mean height of women in country A.
