Question

Do left-hand and right-hand average reaction times differ? To test this, 12 right-handed subjects were randomly selected and the reaction times of their right and left hands, in thousands of seconds, were recorded. The following table contains the results.

Subject 1 2 3 4 5 6 7 8 9 10 11 12

Right 189 96 112 166 115 131 169 158 110 102 182 157

Left 222 168 188 205 195 168 178 169 138 186 152 218 At α = 0.10, test the claim that there is a difference in the average reaction times of the left and right hands. Use the p-value method.

How do I use the p-value method to solve this?
