Question

According to Experian, the average credit score for residents of South Dakota is 700. Suppose the standard deviation for this population is 46.1. A random sample of 60 South Dakota residents has been selected. The standard error of the mean for this sample is ________. 1.96 3.28 5.95 8.44

Answer 1

Answer:

c) 5.95

Standard error of the mean = 5.95

Step-by-step explanation:

Explanation:-

Given mean of the credit score for residents of South Dakota  (x⁻) = 700

Given standard deviation(S.D) ( σ) = 46.1

Random sample size 'n' = 60

Standard error of the mean

                                        $S.E = \frac{S.D}{\sqrt{n} }$

                                        $S.E = \frac{46.1}{\sqrt{60} }$

                                       S.E = 5.95

Conclusion:-

Standard error of the mean = 5.95
