LetXbe normally distributed with mean= 18 and standard deviation= 8. UseTable 1.

http://lectures.mhhe.com/connect/0077639472/Table/table1.jpg

a. FindP(X less than or equal to 0).(Round "z" value to 2 decimal places and final answer to 4 decimal places.)

  1. P(X 0)

b. FindP(X> 4).(Round "z" value to 2 decimal places and final answer to 4 decimal places.)

P(X>greater than 4)

c. FindP(8 X 16).(Round "z" value to 2 decimal places and final answer to 4 decimal places.)

less than or equal to

P(8 X 16)

d. FindP(12X20).(Round "z" value to 2 decimal places and final answer to 4 decimal places.)

12 (less than or equal to ) X less than or equal to)20

P(12 X 20)
