A researcher was interested in comparing the heights of women in two different countries. Independent simple random samples of 9 women from country A and 9 women from country B yielded the following heights (in inches). Country A = 64.1, 66.4, 61.7, 62.0, 67.3, 64.9, 64.7, 68.0, 63.6 Country B = 65.3, 60.2, 61.7, 65.8, 61.0, 64.6, 60.0, 65.4, 59.0 At the 10% significance level, do the data provide sufficient evidence to conclude that the mean height of women in country A is greater than the mean height of women in country B? Assume that the variances are NOT equal. Present boxplots to support the conclusion.

Question
A researcher was interested in comparing the heights of women in two different countries. Independent simple random samples of 9 women from country A and 9 women from country B yielded the following heights (in inches).
Country A = 64.1, 66.4, 61.7, 62.0, 67.3, 64.9, 64.7, 68.0, 63.6
Country B = 65.3, 60.2, 61.7, 65.8, 61.0, 64.6, 60.0, 65.4, 59.0
At the 10% significance level, do the data provide sufficient evidence to conclude that the mean height of women in country A is greater than the mean height of women in country B? Assume that the variances are NOT equal. Present boxplots to support the conclusion.
