Independent random samples were selected from two quantitative populations, with sample sizes, means, and standard deviations given below. n, = n, = 70, x, = 125.1, x2 = 123.4, s, = 5.3, s, = 6.9 Construct a 95% confidence interval for the difference in the population means (u, - H2). (Round your answers to two decimal places.) to Find a point estimate for the difference in the population means. Calculate the margin of error. (Round your answer to two decimal places.) Compare your results. Can you conclude that there is a difference in the two population means (, - H2)? The confidence interval and the point estimate together with the margin of error suggest --Select-- v. Since the value u, - H, = 0 is --Select-- v the interval, the confidence interval suggests it is -Select-- The range of values given by the point estimate the margin of error --Select-- v0. This suggests that the two population means are -Select--

Question

The confidence interval and the point estimate together with the margin of error suggest ---Select--- the same conclusion or different conclusion. Since the value ?1 − ?2 = 0 is ---Select--- in or not in the interval, the confidence interval suggests it is ---Select--- likely the two population means are different or possible the two population means are the same. The range of values given by the point estimate ± the margin of error ---Select--- includes or does not include 0. This suggests that the two population means are ---Select--- possibly the same or probably different.

(Round your answers to two decimal places.) to Find a point estimate for the difference in the population means. Calculate the margin of error. (Round your answer to two decimal places.) Compare your results. Can you conclude that there is a difference in the two population means (u, - µ,)? The confidence interval and the point estimate together with the margin of error suggest -Select--- v. Since the value u, - u, = 0 is --Select--- v the interval, the confidence interval suggests it is ---Select-- . The range of values given by the point estimate i the margin of error -Select-- v 0. This suggests that the two population means are ---Select---
