Under Age of 13 Over Age of 18 n1 = 500 n2 = 600 Number of accidents = 180 Number of accidents = 150 We are interested in determining if the accident proportions differ between the two age groups. Let pu represent the proportion under and p0 the proportion over the age of 18. The null hypothesis is l:> Question 2 8 pts Refer to Question 1. What is the value of the pooled proportion? Round your answer to three decimal places. D' Question 3 8 pts Refer to Questions 1 and 2. Determine the value of the standard error of the difference in the proportions. Round your answer to four decimal places. D Question 4 8 pts Refer to Questions 1, 2 and 3. What is the value of the test statistic? Round your answer to three decimal places. D Question 5 9 pts Refer to Question 4. The p-value is 0 0.0228 0 less than 0.001 O 0.3 0 more than 0.10 D Question 6 9 pts Refer to Questions 1 and 5.
