Question
**Transcription of Educational Material:** --- **7) Problem Statement:** Find the area of the shaded region. The graph depicts the standard normal distribution (z) with mean 0 and standard deviation 1. Round to the nearest tenth. **Diagram Description:** A bell-shaped curve is depicted representing the standard normal distribution. The x-axis is labeled with z-scores: -3.39, -2.26, -1.13, 1.13, 2.26, and 3.39. The shaded region is a central area around the mean, indicating a typical range of values under the normal curve. **Solution Required:** 7) ________ --- **8) Problem Statement:** Suppose that weight of adolescents is being studied by a health organization and that the accompanying table describes the probability distribution for three randomly selected adolescents, where x is the number who are considered morbidly obese. | x | P(x) | |---|-------| | 0 | 0.111 | | 1 | 0.215 | | 2 | | | 3 | 0.224 | Find \( P(x > 1) \). **Solution Required:** 8) ________ --- **9) Problem Statement:** Suppose that replacement times for washing machines are normally distributed with a mean of 8.4 years and a standard deviation of 2 years. Find the replacement time that separates the top 18% from the bottom 82%. Round to the nearest tenth. **Instruction:** Sketch and label a normal curve with the given information. Then, solve the problem. **Solution Required:** 9) ________ --- **10) Problem Statement:** A 28-year-old man pays $181 for a one-year life insurance policy with coverage of $150,000. If the probability that he will live through the year is 0.9994, what is the expected value for the insurance policy? | x | P(x) | |---|------| | | | **Instruction:** Fill in the probability distribution table and find the expected value. **Solution Required:** 10) ________ ---
