5) Rafting down two different rivers took place, 324 boats rafted down the first river, and accidents (capsizing, boat damage, etc.) happened to 35 of them. 92 boats rafted down the second river, and accidents happened to 18 of them. (i) The second river is considered to be more complicated route to raft. Is there evidence for this assumption? Write the null and alternative hypotheses? (Hint: Compare two population proportions) (ii) Use appropriate test statistic to test the hypothesis. Use a = 0.10. ( test statistic in 4 decimal place, critical region for the test statistic) (ili) Construct a 90% one-sided confidence limit for the difference in proportions that can be used to answer the question in part (ii) of 5b) question. ( the bound obtained on the difference in proportions in two decimal place)
