Do the results suggest that texting while driving and driving while drinking are related?
O A. Reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that texting while driving happens 95% of the time when
driving while drinking alcohol.
O B. Fail to reject the null hypothesis. There is not sufficient evidence at a 0.05 significance level to warrant rejection of the claim of independence
between texting while driving and driving while drinking alcohol. Those two risky behaviors are not related.
O c. Reject the null hypothesis. There is sufficient evidence at a 0.05 significance level to warrant rejection of the claim of independence between
texting while driving and driving while drinking alcohol. Those two risky behaviors appear to be somehow related.
