Suppose that a random sample of 41 state college students is asked to measure the length of their right foot in centimeters. A 95% confidence interval for the mean foot length for students at this university turns out to be (21.709. 25.091). If instead a 90% confidence interval was calculated, how would it differ from the 95% confidence interval? A. The 90% confidence interval would be narrower. B. The 90% confidence interval would be wider. C. The 90% confidence interval would be the same as the 95% confidence interval.
