Probability and Statistics Normal Distribution Test
For questions, 1-5 assume that a normal distribution has a mean of 85 and
a standard deviation of 5. Label the graph to accurately reflect this, and
then find the percentages of the data that falls within the specified area
asked by the questions.
1. Between the values of 80 and 90.
2. Between the values of 85 and 95
3. Above 90
4. Below 85
5. Below 95 and above 85
For the following problems, find the area under the standard normal curve.
6. To the left of z = -1.08
7. To the right of z = 1.35
8. Between z= -2.25 and 2 = 2.25
9. To the left of z = -1.45 and to the right of z = 1.96
