What part of a normal distribution is below 295? You have to use Standard Normal

Question

What part of a normal distribution is below 295? You have to use Standard Normal Table (z-score table) to find the answers for following questions. Suppose there is a normally distributed population which has a mean of and a standard deviation of 3. H 440 60, (5p) a. What z-score would correspond to a raw score of 260? b. What raw score would correspond to a z score of -3.5? c. If we randomly select one score from this population, what is the probability that will be less than 550? d. If we randomly select one score from this population, what is the probability that will be greater than 580? What portion of a normal distribution is below 295? e.

Explanation / Answer

z score for the normal distribution = (295 - 440)/60 = 2.4167

look at the z table

probability = 0.78%
