Problem 13

Reaction Time In an experiment conducted online at the University of Mississippi, participants are asked to react to a stimulus such as pressing a key upon seeing a blue screen. The time to press the key (in seconds) is measured and the same person is then asked to press a key upon seeing a red screen, again with the time to react measured. The results for six study participants are shown. Does the evidence suggest that the median reaction time to the blue stimulus is different from the median reaction time to the red stimulus? Use the  = 0.05 level of significance.

Step-by-Step Solution:

Step 1 of 5) Reaction Time In an experiment conducted online at the University of Mississippi, participants are asked to react to a stimulus such as pressing a key upon seeing a blue screen. The time to press the key (in seconds) is measured and the same person is then asked to press a key upon seeing a red screen, again with the time to react measured. The results for six study participants are shown. Does the evidence suggest that the median reaction time to the blue stimulus is different from the median reaction time to the red stimulus Use the = 0.05 level of significance. Finding t-Values Problem Find the t-value such that the area under the t-distribution to the right of the t-value is 0.10, assuming 15 degrees of freedom (df). That is, find t0.10 with 15 degrees of freedom. Approach Step 1 Draw a t-distribution with the unknown t-value labeled. Shade the area under the curve to the right of the t-value, as in Figure 12.
