Question

19. Determine the mean and S.D. of the sampling distribution of means of 300 random samples each of size n=36 are drawn fom a population of N=1500 which is normally distributed with mean u=22.4 and S.D. of 0.048 If sampling is done with replacement, mean of sample is

O A. 15.4

O B. 1122

O C 22.4

D. None of these​

Answer 1

Answer:

1122 is the ans hope this helps

Answer 2

Answer:

The correct answer of this question is 1122.

Step-by-step explanation:

Given - The mean and S.D. of the sampling distribution of means of 300 random samples each of size n=36 are drawn  a population of N=1500.

To Find - Write the mean of sample .

1122 is the mean of sample .

The sampling distribution's standard deviation indicates how much the sample statistic changes from sample to sample. By a factor of n, it is smaller than the population standard deviation. Individual observations are more variable than averages.
