A regional highway uses 8 tollbooths that are open to all vehicles. A chi-square goodness-of-fit test using a significance level of α=0.05 was conducted to determine whether the tollbooths are all used in equal proportions. A chi-square value of χ2=19.1 was calculated with a corresponding p-value of 0.008. Which of the following is correct?
-
a. There is insufficient evidence to suggest that the tollbooths are not used in equal proportions.
-
b. There is insufficient evidence to suggest that the tollbooths are used in equal proportions.
-
c. There is sufficient evidence to suggest that the tollbooths are not used in equal proportions.
-
d. There is sufficient evidence to suggest that the tollbooths are used in equal proportions.
-
e. The tollbooths are used in equal proportions.

A Chi-square goodness-of-fit test was conducted on voter preferences in a state primary (with candidates A, B, C, and D) that yielded a calculated/obtained statistic of 7.82. If you used a critical value of 6.22 to determine if the voters significantly preferred one candidate over another, what conclusion would you draw?
