1.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. Find the probability that a given score is less than 1.28 and draw a sketch of the region.

The probability is

.

(Round to four decimal places asneeded.)

2.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. Find the probability that a given score is less than 2.22 and draw a sketch of the region.

Sketch the region. Choose the correct graph below.

The probability is

(Round to four decimal places asneeded.)

3.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 1.93.

The probability is

(Round to four decimal places asneeded.)

4.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 0.26.

The probability is

(Round to four decimal places asneeded.)

5.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. Find the probability that a given score is between 2.06 and 3.92 and draw a sketch of the region.

The probability is

(Round to four decimal places asneeded.)
