In the distributions shown, state the mean and standard deviation for each. Hint: See Figures 6–5 and 6–6. Also the vertical lines are 1 standard deviation apart.
Answer to relevant QuestionsIn a normal distribution, find σ when µ = 105 and 5.48% of the area lies to the right of 110. The data shown represent the cigarette tax (in cents) for 50 selected states. Check for normality. The mean number of miles driven per vehicle annually in the United States is 12,494 miles. Choose a randomly selected vehicle, and assume the annual mileage is normally distributed with a standard deviation of 1290 miles. ...Use the normal approximation to the binomial to find the probabilities for the specific value(s) of X. a. n = 30, p = 0.5, X = 18 b. n = 50, p = 0.8, X = 44 c. n = 100, p = 0.1, X = 12 d. n = 10, p = 0.5, X ≤ 7 e. n ...For the first 7 months of the year, the average precipitation in Toledo, Ohio, is19.32 inches.
