Question

Complete the following statements by typing your answers in the spaces provided.  If you are asked to determine the probabilities, state your answers to 4 decimal places.  If you are asked to determine a value of Z, state your answers to 2 or 3 decimal places.  Because you will be typing in your answers,  I cannot ask you to draw diagrams as I have done in my previously posted practice finals and solutions to examples, I suggest when you are working on your answers on scrap pieces of paper (or a print out of the exam sheets), draw the diagrams.  You are more likely to get the right answer if you use diagrams.  

1. The P(Z ≤ - 1.74) is _____

2. The P(Z ≥ 0.64) is _____

3. The P(1.24 ≤ Z ≤ 2.72) is _____

4. The value of z such that P(Z ≤ z) = .2061 is _____

5. The value of z such that P(Z ≥ z) = .3050 is _____

6. The value of z such that P(- z ≤ Z ≤ z) = .7960 is _____

7. The value of z that is exceeded 10% of the time is _____
