View Policies Current Attempt in Progress Impact of Sample Size on Accuracy Compute the standard error for sample means from a population with mean y = 80 and standard deviation o = 25 for sample sizes of n = 30, n = 170, and n = 1300. Round your answers to two decimal places. Standard Error Sample Size n = 30: i n = 170 n = 1300 i

Answer 1

Given that the population mean 4 = 80 Population standard deviation o = 25 The standard error of sampling distribution of means is, S.E = where x is the sample size T 25 For n = 30, S.E= = 4.56 V30 25 For n=170, S.E= = 1.92 To 170 25 For n = 1300, S.E= = 0.69 Va 11300
