Question

the mean of a population being sampled is 64, and and the standard deviation is 6.
If the sample size is 50, the standard error of the mean is . (Round off your answer to the nearest hundredth.)

Answer 1

Given:
mean of the population being sampled = 64
standard deviation = 6
sample size = 50

standard error of the mean=standard deviation of the original distribution
                                                                    root of the sample size

standard error of the mean = 6 / √50
standard error of the mean = 6 / 7.07
standard error of the mean = 0.848 or 0.85

Answer 2

The mean of a population being sampled is 64, and and the standard deviation is 6.

If the sample size is 50, the standard error of the mean is 0.85. (Round off your answer to the nearest hundredth.)
