Let's illustrate the idea of a sampling distribution in the case of a very small sample from a very small population. The given

Olegator [25]

Answer:

a: sample mean: 130.2 pounds

This is not the population mean

Step-by-step explanation:

To find the mean weight of the sample, add up all the values and divide by the total number of values entered. In this case, 10, so we have...

mean: (136 + 99 + 118 + 129 + 125 + 170 + 130 + 128 + 120 + 147)/10 =

1302/10 = 130.2

This is not the population mean. It is the mean of the sample. We would have to know more information to make a conjecture about the population mean.
