You perform a chi-squared test for independence on these data to determine if there is an association between having a college degree and one's view on drilling for oil and natural gas. You find that the chi-squared statistic is 11.46 for these data. What is the p-value for this hypothesis test?

Select one:

a. Less than 0.001

b. Between 0.001 and 0.005

c. Between 0.005 and 0.01

d. Between 0.01 and 0.02

Pearson Chi-Square = 11.461, DF = 2, P-Value = 0.003
Likelihood Ratio Chi-Square = 11.46, DF = 2, P-Value = 0.003

0.003 lies between  0.001 and 0.005 so correct option is C.  0.001 and 0.005
