Those test scores are normally distributed with a mean of O and a standard devlation of 1. Find the probability that a given score is less than 2 24 and draw a sketch of the region. Sketch the region. Choose the correct graph below. O A. O B. C. O D. 224 2.24 224 224 2.24 The probability is Round to four decimal places as needed.)

Since the test scores (say "z") are normally distributed with mean 0 and standard deviation 1.So the probability that test scores are less than 2.24 is given by

P(z<2.24) = 0.9875 and the graph in option "c" is the correct.
