A population has a mean of 200 and a standard deviation of 50. Suppose a simple random sample of size 100 is selected and x̅ is used to estimate μ. a. What is the probability that the sample mean will be within ±5 of the population mean? b. What is the probability that the sample mean will be within ±10 of the population mean?

Step 1
- Population mean (\(\mu\)) = 200 - Population standard deviation (\(\sigma\)) = 50 - Sample size (\(n\)) = 100 Show more…

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 used to estimate $\mu .$ a. What is the probability that the sample mean will be within $\pm 5$ of the population mean? b. What is the probability that the sample mean will be within $\pm 10$ of the population mean?

A population has a mean of 200 and a standard deviation of 50. Suppose a sample of size 100 is selected and x is used to estimate μ. (Round your answers to four decimal places.) (a) What is the probability that the sample mean will be within ±5 of the population mean? (b) What is the probability that the sample mean will be within ±10 of the population mean?
