Question 427346: i need to find the z values for a normal distribution
were the mean is 75 and standard deivation is 21
- the probability that exceeds 19%
and were the mean is 21 and the stanard deivation is 6
-the probability the exceed 21%

You can put this solution on YOUR website! i need to find the z values for a normal distribution
where the mean is 75 and standard deviation is 21
- the probability that exceeds 19%
Comment:
a right tail: z = invNorm(0.81) = 0.8779
a left tail: z ininvNorm(0.19) = -0.8779
---
and where the mean is 21 and the standard deviation is 6
-the probability the exceed 21%
Comment:
right tail: z = invNorm(0.79) = 0.8064
a left tail: z = invNorm(0.21) = -0.8064
