State what the given confidence interval suggests about the two population means. 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 Country B 65.3 641 60.2 66.4 617 617 65.8 62.0 61.0 67.3 646 649 600 647 65.4 68.0 59.0 63.6 The following 90% confidence interval was obtlhined for H1-42, the difference between the mean height of women in country A and the mean height of women in country B. -4.34 in. < µ1- H2 < -0.03 in What does the confidence interval suggest about the population means? O The confidence interval includes 0 which suggests that the two population means might be equal. There doesn't appear to be a significant difference between the mean height of women from country A and the mean height of women from country B. O The confidence interval includes only negative values which suggests that the mean height of women from country A is smaller than the mean height of women from country B. O The confidence interval includes only negative values which suggests that the mean height of women from country A is greater than the mean height of women from country B. O The confidence interval includes only negative values which suggests that the two population means might be equal. There doesn't appear to be a significant difference between the mean height of women from country A and the mean height of women from country B.
