An experiment was conducted to compare the mean reaction times to two types of traffic signs: prohibitive
Question:
a. Explain why this is a paired-difference experiment and give reasons why the pairing should be useful in increasing information on the difference between the mean reaction times to prohibitive and permissive traffic signs.
b. Use the Excel printout to determine whether there is a significant difference in mean reaction times to prohibitive and permissive traffic signs. Use the p-value approach.
