Question

for a population with a known variance of 185 a sample of 64 individuals leads to 217 as an estimate of the mean . the standard error of the mean is MCQ

Answer 1

Answer:

6

Step-by-step explanation:

Answer 2

Given: Variance = 185

           No. of individuals= 64 lead to 217

To find: Standard error of the mean

Find:

Variance = sigma²

Since variance is the square of standard deviation

Standard deviation = √variance

                                 = √185

                                 = 13.601

The difference between means samples= n= 217- 65

                                                                      = 153

Standard error of the mean = sigma / √n

                                                 = 13.601/√153

                                                 = 13.601/12.369

                                                  = 1.099

The standard error of the mean is 1.099
