The amount of bleach a machine pours into bottles has a mean of 1080 grams with a standard deviation of 4.5 grams.Suppose we take a random sample of 36 bottles filled by this machine
-The sampling distribution of the sample mean has a standard error of 4.5.

Question

The standard error of the sampling distribution of the sample mean is not equal to the standard deviation of the population. The formula for the standard error is: standard deviation of the population / square root of sample size. In this case, the standard error would be 4.5 / sqrt(36) = 0.75.
