What proportion of a normal distribution is located in the tail beyond a z score of z equals 1.00?
It is 0.158655 or 0.159 approx.is the anwer 0.8413, -0.3413, -0.1587, 0.1587
What percentage of a normal distribution is located in the tail beyond z equals 2.00?
2.27%
What proportion of a normal distribution falls between z equals negative 1.16 and z equals positive 1.16?
1.16/z = -1.16/z * * * * * No! Pr(Z > 1.16) = 0.123 So Pr(-1.16 < Z < 1.16) = 1 - 2*0.123 = 1 - 0.246 = 0.754
An area of a normal probability distribution represents?

What is The normal probability distribution with ยต equals 0 and ฯ equals 1?
It is the Standard Normal distribution.
What sample size is needed to disprove the hypothesis that the probability of outcome A equals 0.25?
The answer depends on what population characteristic A measures: whether it is mean, variance, standard deviation, proportion etc. It also depends on the sampling distribution of A.

Normal distribution it is always true that mean equals median equals mode?
Yes- this can be proved from the normal distribution function.
What proportion of a normal distribution falls between z equals negative 1.16 and z equals positive 1.16?
1.16/z = -1.16/z * * * * * No! Pr(Z > 1.16) = 0.123 So Pr(-1.16 < Z < 1.16) = 1 - 2*0.123 = 1 - 0.246 = 0.754
