A population has a mean of 200 and a standard deviation of 50. Suppose a simple random sample of size 100 is selected and x is u
sed to estimate . a. What is the probability that the sample mean will be within 65 of the population mean
1 answer:
Answer:
z(195) = (195-200)/50 = -0.1
z(205) = (205-200)/50 = +0.1
P(195 < x < 205) = p(-0.1 < z < 0.1) = 0.0797
