Calculate the standard deviaTon of the following scores using the formula and steps
found in Keyton’s online appendix. Make sure that your answer goes out to two decimal
places even if it is a round number. ±he scores for the variable X are below.
9
6
5
7
2

9
7
3
2) Provide the z-score for the following data. ±he formula is (score-mean)/sd, and is in your
notes.
Mean = 52
Standard deviaTon = 35
Raw score = 72
Your answer should be rounded to 2 decimal places.
3) For the following data, compute the percentage of cases that lie below or to the le² of the z-
score that is obtained when X = 50, sd = 10, and mean = 40
Your answer must be in decimal form
4) For the following data, compute the percentage of cases that lie between X
= 100 and
Y= 300, with mean = 200 and sd = 100.
5) Imagine an elecTon with just two candidates. Candidate A asks her consultant to conduct a
poll to see if she (Candidate A) is leading. What is the “null hypothesis” value that is being
“tested” in this example?
Your answer must be expressed as a decimal out to 2 places
