Question 364479: 1. If the random variable z is the standard normal score, is it true that P(-3 < z < 3) > 1? Why or why not?

2. Givent a binomial distribution with n = 29 and p = 0.83, would the normal distribution provide a reasonable approximation? Why or why not?

3. Find the area under the standard normal curve for the following: a). P(z < -0.25) b). P(0.55 < z < 0) c.) P(-1.91 < z < 1.06)
