Question

The use of cellular phones in automobiles has increased dramatically in the last few years. Of concern to traffic experts, as well as to manufacturers of cellular phones, is the effect on accident rates. Is someone who is using a cellular phone more likely to be involved in a traffic accident? What is your conclusion from the following sample information? Use the 0.05 significance level.

Answers

1. The conclusion based on the hypothesis is that do not reject the null hypothesis as the row an column factors are independent.

How to make the conclusion?

From the information given, the null hypothesis is that the row and the column factors are independent. The alternative hypothesis is that they’re dependent.
This was run by using the Chi square test and the following information was gotten:
Test statistic = 2.5234
P- value = 0.1122
Degree of freedom = (2-1)(2-1) = 1
Since the p value is equal to 1%, do not reject the null hypothesis as the row an column factors are independent.
