At the height of the energy shortage during the 1970s, governments were actively seeking ways to persuade consumers to reduce their energy consumption. Among other efforts undertaken, several advertising campaigns were launched. To provide input on how to design effective advertising messages, a poll was taken in which people were asked how concerned they were about shortages of gasoline and electricity. There were four possible

responses to the questions:

Not concerned at all (1)

Not too concerned (2)

Somewhat concerned (3)

Very concerned (4)

A poll of 150 individuals was undertaken. Do these data provide enough evidence to allow us to infer that concern about a gasoline shortage exceeded concern about an electricity shortage?
