Question 13
Phone bills for residents of Shangri-La are normally distributed, with a mean of 98.75 gold coins and a standard deviation of 10.21 gold coins. Random samples of 48 phone bills are drawn from the population and the mean of each sample is determined. Find the standard error of the mean of the indicated sampling distribution.
Round to the ten-thousandths place (4 decimal places), as needed.
State the answer only and no additional work.
SOLUTION:
sampling distribution of standard deviation
= / n = 10.21/ 48
standard error = 1.4737

Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 105 pounds and a standard deviation of 37.3 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined.
The annual salary for one particular occupation is normally distributed, with a mean of about $133 comma 000 and a standard deviation of about $15 comma 000. Random samples of 28 are drawn from this population, and the mean of each sample is determined. Find the mean and standard deviation of the sampling distribution of these sample means. Then, sketch a graph of the sampling distribution. The mean is mu Subscript x over bar equals nothing, and the standard deviation...
