Suppose a random sample of 50 college students are asked to measure the length of their right foot in centimeters. A 95% confidence interval for the mean foot length for students at the college is found to be 21.709 to 25.091 cm. If a 99% confidence interval were calculated instead, how would it differ from the 95% confidence interval?
A. The 99% confidence interval would be wider.
B. The 99% confidence interval would be narrower.
C. The 99% confidence interval would have the same width as the 95% confidence interval.
D. There is no way to tell if the 99% confidence interval would be wider or narrower than the 95% confidence interval.
