Suppose that T and Z are random variables. a. If P(T > 2.02) = 0.05 and P(T

Question:

Suppose that T and Z are random variables.
a. If P(T > 2.02) = 0.05 and P(T < −2.02) = 0.05, obtain P(−2.02 ≤ T ≤ 2.02).
b. Suppose that P(−1.64 ≤ Z ≤ 1.64) = 0.90 and also that P(Z > 1.64) = P(Z < −1.64). Find P(Z > 1.64).
