Answer :
Final answer:
The mean of the sampling distribution of the sample mean is 151, the same as the population mean. The standard deviation of the sampling distribution, or standard error, is 1.5 points.
Explanation:
When officials audit random samples of 36 tests from the LSAT, they are engaging in the process of understanding the sampling distribution of the sample mean. The mean of the sampling distribution will be the same as the population mean, so it remains at 151. The standard deviation of the sampling distribution, also known as the standard error, will be the population standard deviation divided by the square root of the sample size (n).
Therefore, the standard deviation of the sampling distribution is calculated as 9 / √36 which equals 1.5 points
