**Title: Using the Empirical Rule for Quick Probability Approximations**A quick approximation is sometimes useful when an exact answer is not required.### Task:1. **Probability Estimation with the Empirical Rule:** - Given any normally distributed random variable, \( x \), with mean, \( \mu \), and standard deviation, \( \sigma \), use the Empirical Rule to estimate the following probabilities. - **Note:** Probabilities should be reported as numbers between 0 and 1. - \( P(x < \mu + \sigma) = \) - \( P(x < \mu + 2\sigma) = \) - \( P(\mu - 2\sigma < x < \mu + 2\sigma) = \) - \( P(\mu - 3\sigma < x < \mu + 3\sigma) = \) 2. **Specific Calculation Using Given Values:** - Given that \( x \) has a normal probability density function with \( \mu = 5.5 \) and \( \sigma = 8.374 \), use the Empirical Rule to estimate the probability: \( P(-11.248 < x < 13.874) = \)3. **Use the normal probability density function to calculate the probability in part (b).** - **Instruction:** Round your answer to four decimal places. - [Input Box for Answer]- Submit Answer**Navigation:**- View Previous Question- View Next Question- Home - My Assignments - Request Extension**Footer:**- Copyright © 1998 - 2021 Cengage Learning, Inc.

We want to find the following probability by using empirical rule Note: According to bartleby…

A quick approximation is sometimes useful when an exact answer is not required. (a) Given any normally distributed random variable, x, with mean, u, and standard deviation, a, use the Empirical Rule to estimate the following probabilities. (Hint: Don't forget that probabilities should be reported as numbers between 0 and 1.) P(x 2 u + 30) = P(x 2 H- 20) - P(u - o
