Find the mean of the sampling distribution of sample means using the given information. Round to one decimal place, if necessary. \[ \mu=70 \text { and } \sigma=12 ; n=81 \] Answer

Step 1 ：Given that the population mean (\(\mu\)) is 70, the standard deviation (\(\sigma\)) is 12, and the sample size (n) is 81.

Step 2 ：According to the Central Limit Theorem, the mean of the sampling distribution of sample means is equal to the population mean.

Step 3 ：Therefore, the mean of the sampling distribution of sample means is \(\mu = 70\).

Step 4 ：Final Answer: The mean of the sampling distribution of sample means is \(\boxed{70}\).
