A survey asks a random sample of 1500 adults in Ohio if they support an increase in the state sales tax from 6% to 7%, with the additional revenue going to education. Let denote the proportion in the sample that say they support the increase. Suppose that 40% of all adults in Ohio support the increase. The standard deviation of X is closest to:

a. 25.

b. 105.

c. 360.

d. 19.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
