Nationwide Insurance would like to perform a chi-square test to investigate whether a difference exists in the proportion of male and female teenagers who text while they drive
A random sample of 80 male teenagers found that 50 indicated they texted while driving. A random sample of 120 female teenagers found that 65 indicated they texted while driving. Using ? = 0.5, the conclusion for this chi-square test would be that because the test statistic is__________________________________________________________________.A) more than the critical value, we can reject the null hypothesis and conclude that there is a difference in the proportion of male and female teenagers who text while they drive
B) less than the critical value, we can reject the null hypothesis and conclude that there is a difference in the proportion of male and female teenagers who text while they drive
C) more than the critical value, we cannot reject the null hypothesis and conclude that there is no difference in the proportion of male and female teenagers who text while they drive
D) less than the critical value, we cannot reject the null hypothesis and cannot conclude that there is a difference in the proportion of male and female teenagers who text while they drive
