A random sample of Army recruits is selected and given the digit span (a short term memory test) and vocabulary subtests of the Wechsler Adult Intelligence Scale (WAIS). The data are below. What can be concluded with ? = 0.05?

digit span	vocabulary
9 6 12 7 4 5 9 10 8 8 11 9	8 10 8 11 6 11 7 9 10 9 8 10

a) Select and compute the appropriate statistic.
slope =

b) Input the appropriate value(s) to make a decision about H₀.
p-value =

Decision:

c) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
