Where will you get your next pet? Refer to Exercise 4.70 (p. 240) and the associated poll that revealed that half of all pet owners would get their next dog or cat from a shelter.
Consider a random sample of 700 pet owners and define x as the number of pet owners who would acquire their next dog or cat from a shelter. In Exercise 4.70, you determined that x is a binomial random variable.

a. Compute m and s for the probability distribution of x.

b. Compute the z-score for the value x = 338.

c. Compute the z-score for the value x = 374.

d. Use the technique of this section to approximate P1338 6 x 6 3722.
