Suppose that we will take a random sample of size n from a population having mean u and standard deviation e. For each or the following situations, find the mean, variance, and standard deviation of the sampling distribution of the sample mean. a = 10.6= 2n = 25 O Mean = 11. Variance = 0.4. Standard deviation = 0.4 O Mean = 10. Variance = 0.16, Standard deviation - 0.4 O Mean = 10. Variance = 2 Standard deviation - 25 O Mean = 10. Variance = 0.4. Standard deviation = 0.16
