An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below. Under Age of 18 Over Age n1 = 500 n2 = 6 Number of Accidents = 180 Number of Acci We are Interested in determining if the accident proportions differ between the two age groups. Let p, represent the proportion under and Po the proportion over the age of 18. The null hypothesis is O Pu - Po Is not equal to zero Pu - Po Is equal to zero O Pu - Po Is greater than or equal to zero Pu - Po Is less than or equal to zero DETAILS You may need to use the appropriate appendix table or technology to answer this question. Of 325 female registered voters surveyed, 130 indicated they were planning to vote for the incumbent president. Of 405 male registered voters, 142 indicated they were planning to vote for the Incumbent president. (a) Compute the test statistic. (Use female - male. Round your answer to three decimal places.) (b) At a = 0.01, test to see if there is a significant difference between the population proportions of females and males who plan to vote for the incumbent president. (Use the p-value approach.) Calculate the p-value. (Round your answer to three decimal places.) p-value = What is your conclusion? Do not reject Ho. We can conclude that there is a significant difference between the two population proportions. Do not reject Ho. We cannot conclude that there is a significant difference between the two population proportions. Reject Ho. We can conclude that there is a significant difference between the two population proportions. Reject Ho. We cannot conclude that there is a significant difference between the two population proportions
