Chapter 10 1. In a within-subject experiment, subjects (N = 6) completed two visual search tasks, one with a color display and the other with a grayscale display. The orders of task types were counterbalanced. After the experiment, their reaction times (in seconds) were reported. _____ ______EE- .Suppose the researcher want to ask if people 5 reaction times in the color task and the grayscale task are different. Identify the population, the null hypothesis and alternative hypothesis. b. We want to do a paired-samples ttest to test the hypothesis ((1 = .05]. What are the degrees of freedom, the critical tvalue for the test? Calculate the tstatistic from the sample. Make a decision for your hypothesis testing. Calculate the 95% Confidence Interval. How does this Confidence Interval relate to your decision in d)? moan
