Question

A population has a mean of

122

.

If a random sample of

8

items from the population results in the following sampled values, what is the sampling error for the sample

100 147 97 127 141 144 101 130

Answer 1

Answer #1

Sampling error of mean is the difference between population mean and sample mean

Population mean = 122

Sample mean = (100 + 147 + 97 + 127 + 141 + 144 + 101 + 130)/8

= 123.375

Sampling error = 123.375 - 122

= 1.375
