Answer:
The standard error for the sampling distribution is 1.323.
Step-by-step explanation:
Let <em>X</em> = scores of girls and <em>Y</em> = scores of boys.
The information provided is:

As the population standard deviations are not known, use a pooled standard deviation to estimate the standard error of the sampling distribution.
The formula of pooled standard deviation is:

Compute the standard error for the sampling distribution as follows:

Thus, the standard error for the sampling distribution is 1.323.
1 large slice (41g) of whole grain has 1.7g of fat. This is a little over 4%.
