In the EAI sampling problem, we showed that for n = 30, there was .5064 probability of obtaining a sample mean within +/- $500 of the population mean. a. What is the probability that is within $500 of the population mean if a sample size of 60 was used?
b. What is the probability that is within $500 of the population mean if a sample size of 120 was used?

step-by-step explanation:

their are no angles. sorry cant .

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:
