For the data 95 10 7 9 10 11 8 12 7 6 9, find the raw scores that correspond to the following : z= +1.22; z= -0.48

1 answer

you have to find the mean and the standard deviation of the data.

mean = 16.7 sd =26.02 this is if the first number is 95, but I am thinking you meant 9 and 5.

mean =8.58
sd = 2.065

To find a z-score subtract the mean from the given value and divide by the sd.
