A 99% confidence interval for the mean sugar content (per 5 oz. serving) of a shipment of strawberries is 5.9 to 8.3 grams

If we chose to calculate a 95% confidence interval using the same data instead of calculating a 99% confidence interval, which of the following would describe the change in width of the interval?

(a) It would be wider.

(b) It would be narrower.

(c) The margin of error would be the same, but the center of the interval would be different.

(d) It would be the same margin of error and same center.

(e) Since the sample mean is a random variable, we cannot predict how the 95% confidence interval would change.
