Assume that x has a normal distribution, with the specified mean and standard deviation. Find the indicated probabilities.
6)P(40 less than or equal to x less than or equal to 47); u = 50; o = 15
10) P( x greater than or equal to 2); u = 3; o = 0.25
Find the z value described and sketch the area described.
14) find z such that 97.5% of the standard normal curve lies to the left of z.
18) find z such that 95% of the standard normal curve lies to the right of z.
