1) What is the probability that Z is less than minus 0.23 or greater than themean. (Mean- 0, Standard Dev- 1)

2) Given a normal distribution with =50 =4, and given you select a sample of n=100,

There is a 35% chance that X is above whatvalue?

3) With 41 observations, the smallest of the standard normal quantile values covers an area under the normal curve of __/42 = __ . The correspondingZ-value is 1.98. The largest of the standard normal quantile values covers an area under the normal curve of __/42 = __. The correspondingZ-value is +1.98. The middle of the standard quantile values covers an area under the normal curve of __/42 = __. The correspondingZ-value is 0.00.
