Fred and Ted are interested in the average height of NC State students. They randomly sample students from NC State and construct confidence intervals from their data. Fred sampled 121 students to construct his confidence interval. Ted sampled 144 students to construct his confidence interval; both create histograms for their data which have symmetric, unimodal, and roughly bell- shaped distributions. Which of the following is true about the margins of error for these experiments? Select one: O a. We are unable to determine which margin of error is larger without knowing more about Fred and Ted's samples. O b. Fred and Ted have the same size margins of error. Ос. Ted's margin of error is larger than Fred's. O d. Fred's margin of error is larger than Ted's.

Question
Fred and Ted are interested in the average height of NC State students. They randomly sample
students from NC State and construct confidence intervals from their data. Fred sampled 121
students to construct his confidence interval. Ted sampled 144 students to construct his confidence
interval; both create histograms for their data which have symmetric, unimodal, and roughly bell-
shaped distributions. Which of the following is true about the margins of error for these
experiments?
Select one:
We are unable to determine which margin of error is larger without knowing more about
Fred and Ted's samples.
a.
O b. Fred and Ted have the same size margins of error.
Ос.
Ted's margin of error is larger than Fred's.
Od.
Fred's margin of error is larger than Ted's.
