Using the same X , s x , and level of confidence, suppose that n were 69

Question:

Using the same X̅ , sx , and level of confidence, suppose that n were 69 instead of 39. Would the error bound become larger or smaller? How do you know?

The data in Table 8.2 are the result of a random survey of 39 national flags (with replacement between picks) from various countries. We are interested in finding a confidence interval for the true mean number of colors on a national flag. Let X = the number of colors on a national flag.
