Suppose a random sample of 50 college students is asked if they
regularly eat breakfast. A 95% confidence interval for the
proportion of all students that regularly eat breakfast is found to
be 0.69 to 0.91. If a 90% confidence interval was calculated
instead, how would it differ from the 95% confidence interval?
The 90% confidence interval would be wider.
The 90% confidence interval would be narrower.
The 90% confidence interval would have the same width as the 95%
confidence...
