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 between -1.62 and 1.62. Sketch the region. Choose the correct graph below: A B C D The probability is (Round to four decimal places as needed:)

Step 1
62 and -1.62 using the formula z = (x - mean) / standard deviation. For 1.62: z = (1.62 - 0) / 1 = 1.62 For -1.62: z = (-1.62 - 0) / 1 = -1.62 Show more…

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 -1.51. Sketch the region. Choose the correct graph below. The probability is . (Round to four decimal places as needed.)

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 $1 .$ In each case, draw a graph, then find the probability of the given bone density test scores. If using technology instead of Table $A-2,$ round answers to four decimal places. Less than -1.96
