Suppose the population has a mean of 450 and a variance of 900. If a random sample of size 100 is drawn from the population, what is the probability that the sample mean is between 448 and 453? The probability is 0.4972.

Step 1
We know that the population mean is 450 and the variance is 900. This means that the standard deviation of the population is √900 = 30. Show more…

A population with a mean of 1,400 and a standard deviation of 400 is known to be highly skewed to the right. If a random sample of 49 items is selected from the population, what is the probability that the sample mean will be less than 1,500? P(̄x < 1,500) = (Round to four decimal places as needed.)
