Answer:
48 and 4
Step-by-step explanation:
If we assume that to be the random variable that proceed the normal distribution with mean
and a standard deviation
Given that:
mean =48
standard deviation = 16
sample size = 16
The population mean is same as the population mean in sampling distribution that is 48.
The standard deviation of the sampling distribution is therefore calculated as:
standard deviation =
standard deviation =
standard deviation =
standard deviation = 4
Thus; the mean and the standard deviation of the sampling distribution is 48 and 4
