A random sample size of 175 is drawn from a large population. The population standard deviation is 13.6. The sample mean is 87.3. Estimate the size of the population mean, including the margin error.

The size of the population mean would be provided as:

mean +/- std/sqrt(sample size)

<=>

87.3 +/- 13.6/sqrt(175)

<=>

87.3 +/- 1.03

=> Option B is correct.

Hope this helps!
