Question
A 95% confidence interval for the true proportion of math students who prefer to use a handheld calculator versus computer software for computations is (0.751, 0.863). Is it reasonable to believe more than 75% of math students prefer to use a handheld calculator versus computer software for computations?
Yes, because the entire interval is greater than 0.75.
Yes, because the center of the interval is 0.807, which is greater than 0.75.
No, because a different sample might give different results.
No, because 0.751 is barely greater than 0.75, which is not statistically significant.
