Identify the appropriate test statistic to be used in each problem from the terms inside the box. A. t-test B. Central Limit Theorem C. chi-square test D. z-test 16. What appropriate tool is applicable if the population is normal, sample standard deviation is known, and sample is less than 30? 17. The supervisor of a certain company claimed that the mean workday of his workers is 8.3 hours per day. A sample of 20 workers was taken and it was found out that the mean workday is 8 hours with standard deviation of 1 hour. At 0.01 level of significance, is the mean workday less than 8.3 hours? What test statistic is to be used in the given problem? 18. A leader of an association of jeepney driver claims that the average daily take-home pay of all jeepney drivers in Caloocan is P350.00. A random sample of 100 jeepney drivers in Caloocan was interviewed and the take-home pay was found to be P420.00. If 0.05 significance level was used to find out whether the average take home pay is different from P350.00 and population variance was assumed to be P92.00, what is the appropriate test statistic? 19. L.V. Co. has an average sale of P37 million per week from their products in all their outlets. An area manager found out that the average gross sales from the 28 outlets under her jurisdiction is P32.5 million per week with standard deviation of P1.5 million. Does the mean sales of all outlets differ from the mean sales of the 28 outlets under her jurisdiction? In the given problem, what statistical tool is suitable to use? 20. According to a study, there is an increase on average monthly expenses of P250.00 for cell phone loads of Senior High School students in the city. Is there a reason to believe that the amount increased if sample of 60 students has an average monthly expense of P280.00 and the population ståndard deviation is P77.00? What is the tool to be used in computing the test value?
