Juries should have the same racial distribution as the surrounding communities. According to the U.S. Census Bureau, 18% of residents in Minneapolis, Minnesota, are African Americans. Suppose a local court will randomly sample 100 state residents and will then observe the proportion in the sample who are African American. How likely is the resulting sample proportion to be between 0.066 and 0.294 (i.e., 6.6% to 29.4% African American)?

There is roughly a 95% chance that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion.

There is roughly a 99.7% chance that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion.

There is roughly a 68% chance that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion.

It is certain that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion.
