the indicated probability. Probability of fewer than 3 passengers who do not show up for a flight Choose the correct answer below. OA. The area to the right of 2.5 OB. The area to the right of 3.5 OC. The area to the left of 3.5 O D. The area between 2.5 and 3.5 O E. The area to the left of 2.5

Use the TI-84 calculator to find the z-score for which the area to its right is 0.46. Round the answer to two decimal places.

?) H Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the probability of a bone density test score greater than 0.31. Sketch the region. Choose the correct graph below. A. В. O C. O D. -0.31 0.31 0.31 -0.31 0.31 The probability is.
