Exercise 5.8.12 The percent of persons (ages 5 and older) in each state who speak a language at home other than English is approximately exponentially distributed with a mean of 9.848 . Suppose we randomly pick a state. (Source: Bureau of the Census, U.S. Dept. of Commerce) a. Define the random variable. X = b. Is X continuous or discrete? c. X~ d. = e. = f. Draw a graph of the probability distribution. Label the axes. g. Find the probability that the percent is less than 12. h. Find the probability that the percent is between 8 and 14. i. The percent of all individuals living in the United States who speak a language at home other than English is 13.8 . i. Why is this number different from 9.848%? ii. What would make this number higher than 9.848%?
