Length of a rod: engineers on the bay bridge are measuring tower rods to find out if any rods have been corroded from salt water. there are rods on the east and west sides of the bridge span. one engineer plans to measure the length of an eastern rod 25 times and then calculate the average of the 25 measurements to estimate the true length of the eastern rod. a different engineer plans to measure the length of a western rod 20 times and then calculate the average of the 20 measurements to estimate the true length of the western rod. suppose the engineers construct a 90% confidence interval for the true length of their rods. whose interval do you expect to be more precise (narrower)? group of answer choices both confidence intervals would be equally precise. the engineer who weighed the rod 25 times. the engineer who weighed the rod 20 times.
