A random sample of n measurements was selected from a population with standard deviation o = 18 and unknown mean μ. Calculate a 90 % confidence intervalfor μ for each of the following situations:(a) n = 40, x= 75.7<με(b) n = 60, x= 75.7sus(c) n = 75, x = 75.7OSASthe margin of error (width) of the confidence interval. (Enter:(d) In general, we can say that for the same confidence level, increasing the sample size"DECREASES", "DOES NOT CHANGE" or "INCREASES", without the quotes.)

As per company guidelines I solved exactly three subparts of the question.thank you
