According to the z distribution, what proportion of SAT verbal scores fall between 200 and 800? standard deviation of an SAT score is 100, SAT mean of 500. .3413 .2500 .5000 .9970

Assume that all SAT scores are normally distributed with a mean μ = 1518 and a standard deviation σ = 325. If 100 SAT scores (n = 100) are randomly selected, find the probability that the scores will have an average less than 1500. TIP: Make the appropriate z-score conversion 1st, and then use Table A-2 to find the answer. 0.7088 0.55 - 0.55 0.2912
For a distribution of scores, X=20 corresponds to a z-score of z=+1.00, and X=26 corresponds to a z-score of z = -.50. What are the values for the mean and standard deviation for the distribution?
