Suppose a town records data on collisions at intersections and a city planner would like to check whether the severity of the collisions (fatality, injury, or non-injury) is dependent on the type of intersection at which the collisions occur. The available data for one year is summarized below: traffic signal with traffic signal with 2-way stop 4-way stop no left turn signal left turn signal non-injury 9 18 injury No 15 10 at least one 0 3 fatality (a) State the null and alternative hypotheses. (b) Use technology to calculate the test statistic. (c) Determine the degrees of freedom for this test. (d) Use technology to determine the P-value and state the decision. (e) State the conclusion of the test in the terms of the claim that is being tested! Edit View Insert Format Tools Table 12pt Paragraph BIUAL
