A random sample of five jobs from the accounting department in the past week and six jobs from the research department in the past week are selected. It is given that the population variances are equal. The processing time (in seconds) for each job is recorded in Table below. Department Processing time (in seconds) Accounting Research Determine whether there is enough evidence to conclude that there is a difference between the mean processing time of the accounting department and that of the research department by using a level of significance of 0.05. QUESTION 2 A manufacturer of automobile shock absorbers was interested in comparing the durability of its shock absorbers with that of the shock absorbers produced by its biggest competitor. To make the comparison, one of the manufacturer's and one of the competitor's shock absorbers were randomly selected and installed on the rear wheels of each of six cars. After the cars had been driven 20,000 kilometres, the strength of each test shock absorbers was measured, coded and recorded. It is given that the population variances are equal for both groups. The results of the examination are shown in the Table below. Car number Manufacturer's shock absorbers Competitor's shock absorbers 8 8 10.1 N 10.5 125 12.0 9.6 13.2 13.0 Determine whether there is sufficient evidence to conclude that there is a difference in the mean strength of the two types of shock absorbers after 20,000 kilometres of use by using a level of significance of 0 05.
