What is the probability that the sample mean is less than 2.50 inches? P(x <2.50) = Round to four decimal places as needed.)
Added by Erica S.
Step 1
50 inches using the formula: \[ z = \frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}}} \] where - \(\bar{x}\) = sample mean - \(\mu\) = population mean - \(\sigma\) = population standard deviation - \(n\) = sample size Show more…

Suppose that a random sample of size 64 is to be selected from a population with mean 40 and standard deviation 5. a) What is the approximate probability that x will differ from μ by more than 0.8? (Round your answer to four decimal places.)

Suppose that a random sample of size 100 is to be selected from a population with mean 50 and standard deviation 6. what is the approximate probability that x will be within 0.4 of the population mean μ? (Round your answer to four decimal places.)

A population with a mean of 1,150 and a standard deviation of 320 is known to be highly skewed to the right. If a random sample of 64 items is selected from the population, what is the probability that the sample mean will be less than 1,200? P(x < 1,200) = (Round to four decimal places as needed.)
