WPC Sports Company has noted that the size of individual "customer order" is normally distributed with a mean of $100 and a standard deviation of $12. If a soccer team of 16 players was to make the next batch of orders, what would be the standard error of the mean?

The standard error of the mean is 3.

Step-by-step explanation:

We are given that WPC Sports Company has noted that the size of individual "customer order" is normally distributed with a mean of $100 and a standard deviation of $12.

A soccer team of 16 players was to make the next batch of orders.

Since we know that the confidence interval is created by the given formula;

Suppose we have to calculate 95% confidence interval;

So, 95% Confidence interval = Sample mean Margin of error

where, Sample mean = = $100

Margin of error =

Here, = standard deviation = $12

          n = sample of players = 16

So, Standard error formula is given by =

                                                                  = = 3

Therefore, standard error of the mean for this sample is 3.
