Question 14 What can we say about the two probabilities az Question 14 2 Points What can we say about the two probabilities P(-a<z<0) and P(0<z<a), where a is any real positive value of z? Impossible to say. We need to know what a is. The two probabilities are equal. The two probabilities are not equal. The two probabilities are equal in magnitude but opposite in sign

2. Consider the probability distribution function for the random variable z. a. Is this a valid probability distribution? Why or why not? b. What is the probability that z is at least 35? c. What is the probability that z less than or equal than 70? z | f(z) 50 | 0.15 75 | 0.2 15 | 0.3 20 | 0.1 35 | 0.25

Question 1 4 pts Use a calculator to find the value of z* that yields the probability shown: 1. P(Z < z*) = 0.3300 2. P(Z < z*) = 0.9901 3. P(Z > z*) = 0.0055 4. P(Z > z*) = 0.7995
