Question:

What are travelers' technologies of choice? Tablets account for a growing share of the multiuse devices travelers are using. An observational study of passengers on air, bus, and train travel found that 8.4% of airline passengers, 5.9% of Amtrak passengers, 4.9% of commuter train passengers, and 3.7% of curbside bus passengers were observed using a tablet at some point during their travel. (Data extracted from afterhours.e-strategy.com/passenger-tablet-use-by-transportation-mode-c.) Suppose these results were based on 500 passengers in each of the four transportation modes: airline, Amtrak train, commuter train, and curbside bus.
a. At the 0.05 level of significance, is there evidence of a difference among the transportation modes with respect to use of tablets?
b. Compute the p-value and interpret its meaning.
c. If appropriate, use the Marascuilo procedure and a = 0.05 to determine which transportation modes differ.
