What fraction of a gallon is a quart

Step-by-step explanation:

The standard error is used to determine the difference between the sample mean of the data and the true population mean.

Standard error = population standard deviation/square root of the number of samples

Given that the sample mean foot length of a simple random sample of 25 third-graders is 22.5 cm and the standard error of the mean is 0.8 cm, the correct interpretation for the standard error of the mean is

D. The typical distance between means of samples of size 25 and the population mean foot length is approximately 0.8 cm
