Question

If random samples of size 70 are drawn from a population with a mean of 55 and a standard deviation of 27, find the standard error of the distribution of sample means. Do not round.

Answer 1

The standard error of the distribution of sample means can be calculated using the formula: standard error = standard deviation / square root of sample size. In this case, the standard error is approximately 3.229.

Step-by-step explanation:

The standard error of the distribution of sample means can be calculated using the formula:

standard error = standard deviation / square root of sample size

in this case, the population has a mean of 55 and a standard deviation of 27. Since the sample size is 70, we can calculate the standard error as follows:

standard error = 27 / sqrt(70)

Therefore, the standard error of the distribution of sample means is approximately 3.229.
