Question

Consider an x distribution with standard deviation 24 (a) If specifications for a research project require the standard error of the corresponding x distribution to be 2, how large does the sample size need to be? (b) If specifications for a research project require the standard error of the corresponding x distribution to be 1, how large does the sample size need to be? n =

Answer 1

Solution :- *) Given that Standard deviation , r =24 Here Standard error = - = SE (a) Nowo From the given data SE = 2 = (la)2 (n= 144) (b) Here SE = 1 → The Sample size, no (24)2 = (2412 n = 576 OG *** Thanking you -
