Reconsider the previous question about hours spent watching TV every day. Suppose that the data had actually been collected from a sample of 150 students, and not 100, but everything else (mean and SD) was the same as reported earlier. How, if at all, would the new 95% confidence interval based on these data differ from the interval mentioned earlier: (2.619, 3.401) hours?
a. The new interval would still be (2.619, 3.401) hours, because we are still 95% confident.
b. The new interval would be narrower than (2.619, 3.401) hours, because the sample size is bigger.
c. The new interval would be wider than (2.619, 3.401) hours, because the sample size is bigger.
d. More information is needed to answer this question.
