Question 5 of 6 Step 1 of 3 A student researcher compares the heights of American students and non-American students from the student body ofa certain college in order to estimate the difference in their mean heights. A random sample of 12 American students had a mean height of 67.7 _inches with a standard deviation of 3.06 inches A random sample of 17 non-American students had a mean height of 64.7 inches with a standard deviation of 1.97 inches. Determine the 90 % confidence interval for the true mean difference between the mean height of the American students and the mean height of the non-American students. Assume that the population variances areeqyal and that the two populations are normally distributed. Step 1 of 3: Find the point estimate that should be used in constructing the confidence interval.
