A survey of entrepreneurs focused on their job characteristics, work habits, social activities, leisure time, etc. One question put to each entrepreneur was, "What make of car (U.S., Europe, or Japan) do you drive?" The responses (number in each category) for a sample of 100 entrepreneurs are summarized below. The goal of the analysis is to determine if the proportions of entrepreneurs who drive American, European, and Japanese cars differ.
In order to determine whether the true proportions in each response category differ, a one-way chi-square analysis should be conducted. Suppose the p-value for the test was calculated to be
. What is the appropriate conclusion to make when testing at α = 0.10?
◦ There is sufficient evidence to indicate the proportion of entrepreneurs driving the three makes of car are equal.
◦ There is insufficient evidence to indicate the proportion of entrepreneurs driving the three makes of car differ.
◦ There is sufficient evidence to indicate the proportion of entrepreneurs driving the three makes of car differ.
◦ There is sufficient evidence to indicate the proportion of entrepreneurs driving Japanese cars is less than the proportion driving U.S. cars.
