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. 7) 7) -3.39 -2.26 -1.13 1.13 2.26 3.39 2 8) Suppose that weight of adolescents is being studied by a health organization and that the accompanying tables describes the probability distribution for three randomly selected adolescents, where x is the number who are considered morbidly obese. 8) P(x) 0.111 1 0.215 2 3 0.224 Find P( x>1). Sketch and label a normal curve with the given information. Then, solve the problem. Round to the nearest tenth. 9) 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%. 9) Fill in the probability distribution table and find the expected value. 10) 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? 10) X P(x)
