2. Suppose that X is a normally distributed random variable with u =5 and o 3. Use the standard normal probability table to calculate a value of X, call it xo, for parts a, b, and c; the rest are optional, for extra practice. Illustrate your answers with graphs. You are given a probability associated with a particular value of X, and you must calculate the x value using a z-score and the Z table. (4) a. P(X < xo) = 0.8413 b. P(X > x) = 0.025 c. 1% of the values of X are greater than xo. Hint: In other words, find the 99th percentile. d. P(X > xo) = 0.95 e. P(41 < X < xo) = 0.8630 f. 10% of the values of X are less than xo. Hint: In other words, find the 10th percentile.
