Question: In the EAI sampling problem, the population mean is $71,800 and the population standard deviation is $4,000. When the sample size is n = 30,

In the EAI sampling problem, the population mean is $71,800 and the population standard deviation is $4,000. When the sample size isn= 30, there is a .5064 probability of obtaining a sample mean within +/- $500 of the population mean.

1.What is the probability that x is within 500 of the population mean if a sample of size 60 is used (to 4 decimals)?

Answer part (a) for a sample of size 120 (to 4 decimals).
