Question

Where ranges are given as choices, pick the correct range. For example, if you calculate a probability to be 0.27, you would pick 0.2-0.3. If your answer is 0.79, your choice would be 0.7-0.8, and so on. The random variable Z has a standard normal distribution.

1) Compute the probability that Z<0.6.

0.4-0.5
0.5-0.6
0.6-0.7
0.7-0.8
0.8-0.9
0.9-1
