Hello I need help with this question for my class
HW 7 CLT: Problem 6 (1 point) A random sample of n measurements was selected from a population with standard deviation o = 12.5 and unknown mean μ. Calculate a 95% confidence interval for μ for each of the following situations: (a) n = 60, x = 90.4 <m< (b) n = 90, x = 90.4 <m< (c) n = 105, x = 90.4 <m< (d) In general, we can say that for the same confidence level, increasing the sample size the margin of error (width) of the confidence interval. (Enter: "DECREASES", "DOES NOT CHANGE" or "INCREASES", without the quotes.)
