Question

A sample of size \( n = 60 \) is drawn from a population whose standard deviation is \( \sigma = 33 \).

### Part 1 of 2

(a) Find the margin of error for a 90% confidence interval for \( \mu \). Round the answer to at least three decimal places.

The margin of error for a 90% confidence interval for \( \mu \) is [ ].

### Part 2 of 2

(b) If the sample size were \( n = 82 \), would the margin of error be larger or smaller?

[Choose one] , because the sample size is [Choose one].
