A Gallup poll conducted in 2011 asked respondents why they would not consider buying a hybrid car for their next purchase. The results are shown in the following table.

Suppose Toyota would like to confirm these results with its own survey, so the company asked 300 people the same question. The results of Toyota’s survey are also shown in the following table:

Reason Gallup Poll (%) Toyota Too expensive 39 104 Technology not proven 19 50 Inconvenient to use 9 33 Poor performance 8 33 Something else 21 56 No opinion 4 24 Total 100 300

a. Using a = 0.05, determine if the observed frequencies in the Toyota survey are consistent with the results from the Gallup poll.

b. Determine the p-value using Excel and interpret its meaning.
