Question

Compare the widths of the confidence intervals.

a. The 90% confidence interval is (Round to two decimal places as needed).
b. The 95% confidence interval in Found is (Round to two decimal places as needed).

Answer 1

The 95% confidence interval is wider than the 90% confidence interval because it captures a larger range of possible values.

Step-by-step explanation:

The widths of the confidence intervals can be compared by looking at the range of values they encompass. In this case, the 90% confidence interval is (67.18, 68.82) and the 95% confidence interval is (67.02, 68.98). The 95% confidence interval is wider because it captures a larger range of possible values as it includes a higher level of confidence.
