Compute the standard error of a sampling distribution.
-A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. However the
Pizza chain has certain specifications regarding the amount of cheese filling in its ravioli.
Suppose quality control inspectors at this pizza restaurant chain sample 100 ravioli from
An incoming shipment. They find a sample average of 16 grams with a standard
Deviation of 1.8 grams. What is the standard error of the sampling distribution of the
Sample mean?
A) 1.8 grams
B) 1.6 grams
C) 0.18 grams
D) 0.16 grams
E) 0.018 grams

Quizplus · Accepted Answer

The standard error of the sampling distribution of the sample mean is the standard deviation of the sample divided by the square root of the sample size. In this case, the standard deviation of the sample is 1.8 grams and the sample size is 100. Therefore, the standard error of the sampling distribution of the sample mean is 1.8 / sqrt(100) = 0.18 grams.
