Calculate standard deviation showing all working
![**C. Mean for this Distribution of Sample Mean**
The formula for the mean is given by:
\[
\mu_{x} = \frac{(81.0 + 75.0 + 77.5 + 79.0 + 76.0 + 78.5 + 80.0 + 72.5 + 74.0 + 76.5)}{10} = 77.0
\]
The results can be used to make informed decisions about the population mean because it represents a sample of the entire population. Therefore, the informed decision regarding the population mean is as follows: as sample sizes increase, the chance of getting the true population mean improves.
