- According to the report about the survey performed by Company XYZ that 60% of the people think that violence has increased in the oast 4 years. In a future random sample of 250 people in a certain age of more 20 years old group, if we let X be the number of such people in that sample who think that the proposal is correct. a) What is the approximate distribution of X with parameters?If the expected return on the market is 8% and the risk for your rate is 4%. What is the expected return for a stock with a beta equal to 2.00? Let X be a continuous random variable with mean μ and standard deviation σ.

- The United States Department of Agriculture (USDA) found that the proportion of young adults ages 20–39 who regularly skip eating breakfast is 0.238. Suppose that Lance, a nutritionist, surveys the dietary habits of a random sample of size ?=500 of young adults ages 20–39 in the United States. Apply the cnormal to find the probability that the number of individuals, ?,X, in Lance's sample who regularly skip breakfast is greater than 122. You may find table of critical values helpful. Express the result as a decimal precise to three places. ?(?>122)= Apply the central limit theorem for the binomial distribution to find the probability that the number of individuals in Lance's sample who regularly skip breakfast is less than 103. Express the result as a decimal precise to three places. ?(?<103)=A marriage counselor has traditionally seen that the proportion p of all married couples for whom her communication program can prevent divorce is 79%.
