Solved: The reaction times for two different stimuli in a
Chapter 13, Problem 1E(choose chapter or problem)
The reaction times for two different stimuli in a psychological word-association experiment were compared by using each stimulus on independent random samples of size 8. Thus, a total of 16 people were used in the experiment. Do the following data present sufficient evidence to indicate that there is a difference in the mean reaction times for the two stimuli?
a Use the ANOVA approach to test the appropriate hypotheses. Test at the \(\alpha=.05\) level of significance.
b Applet Exercise Use the applet F-Ratio Probabilities and Quantiles to determine the exact -value for the test in part (a).
c Test the appropriate hypotheses by using the two-sample test for comparing population means, which we developed in Section 10.8. Compare the value of the t statistic to the value of the
statistic calculated in part (a).
d What assumptions are necessary for the tests implemented in the preceding parts?
