If the 78% confidence interval is from 87 to 133, what would the 97% confidence interval be?

The 97% confidence interval would be from 108 to 165.

Step-by-step explanation:

Since the 78% confidence interval is from 87 to 133, to determine what the 97% confidence interval would be, the following calculations must be performed:

78 = 87

97 = X

97 x 87/78 = X

8.439 / 78 = X

108.19 = X

78 = 133

97 = X

97 x 133/78 = X

12.901 / 78 = X

165.39 = X

Thus, the 97% confidence interval would be from 108 to 165.
