### Sample Mean Probability QuestionsYou may need to use the appropriate appendix table or technology to answer this question.A population has a mean of 200 and a standard deviation of 50. Suppose a sample of size 100 is selected and $\bar{x}$ is used to estimate $\mu$. (Round your answers to four decimal places.)#### (a) What is the probability that the sample mean will be within $\pm 5$ of the population mean?\[ \textcolor{red}{\textbf{X}} \]#### (b) What is the probability that the sample mean will be within $\pm 10$ of the population mean?\[ \textcolor{red}{\textbf{X}} \]#### Need Help?- [![Read It](https://educationsite.com/readit)](https://educationsite.com/readit)- [![Watch It](https://educationsite.com/watchit)](https://educationsite.com/watchit)---In this exercise, you are asked to determine the probability that the sample mean will be within a certain range of the population mean. The provided details include:- The population mean ($\mu$) is 200.- The standard deviation ($\sigma$) is 50.- The sample size ($n$) is 100.Two specific questions are posed:1. The probability that the sample mean is within $\pm 5$ of the population mean.2. The probability that the sample mean is within $\pm 10$ of the population mean.Appropriate tools like statistical tables or software should be used to find the probabilities, and results should be rounded to four decimal places. The 'X' symbols indicate areas where responses are expected. Interactive 'Need Help?' options are provided as 'Read It' and 'Watch It' to offer additional explanations and video assistance.
