Refer to the data in Exercise 1 above. Perform a Kolmogorov-Smirnov one-sample test to examine the normality of this sample of scores. Your response should be organized according to the 8 steps in hypothesis testing. Report your findings. (10 points)

Hypothesis Testing Steps 1-3 (1.5 points)

For Hypothesis Testing Step 4, calculate the test statistic using the following process:

Create a frequency distribution table to provide a summation of the scores (1 point)

Calculate the midpoint for the observed frequency distribution of scores (using formula 2.11 on page 28); use SPSS to obtain the standard deviation for this sample of scores. (1 point)

Determine the z-scores for each value in the distribution and its corresponding probability values (2 points)

Calculate the relative frequencies for the empirical and observed distributions. (2 points)

Use SPSS to compute the value of K-S test for the set of scores, and test the hypothesis. Attach the SPSS printout. (1 point)

Complete the Hypothesis Testing procedure Steps 5 to 8. (1.5 points) #### Earn Coins
