B)A math test has a mean of 49 and standard deviation of 6.0. I need to the the corresponding z scores for: a test score of 36 and a test score of 78.
Hi
A) entering data in an Excel column and using the data analysis tool
mean = 20.0667 , varience = 180.2095, standard deviation = 13.4242
B) z = (36-49) /6 and z = (78-49)/ 6
