Dear Tutor,

I have task below, please assist me to answer with detail step by step, explaning by curve or graph and formula how to get it ( note : clear writting and no scribbles cause i will save for my file document for study)

Taxi companies want to determine whether the use of radial tires compared to regular tires can save fuel or not. A total of 12 cars equipped with radial tires, tried in a predetermined route. Without changing the driver, the tires of the same cars are then replaced with regular tires and tried once again on the same route. Its fuel consumption is recorded (in kilometers per liter). Using the help of Minitab software obtained the following output: Welcome to Minitab, press F1 for help. Paired T-Test and Cl: radial,usual Paired T for radial regular N Mean StDev SE Mean radial 12 5.750 1.053 0.304 regular 12 5.608 0.994 0.287 Difference 12 0.1417 0.1975 0.0570 95% CI for mean difference: (0.0162r 0.2672) TTest of mean difference = 0 (VS # 0): TValue = 2.48 P Value = 0.030 3. Based on the output ofthe Minitab above, and using (1 = 0.04 can it be concluded that cars with radial tires are more iel efcient than cars with regular tires? b. At a confidence rate of 95%, write down an estimated interval of the average difference in fuel consumption between the car and radial tires and regular tires. 2. A study of final semester students at a public college on the interests of working in government agencies (State Civil Apparatus, SCA) looks like the table below: _ Student Worklng Interests Man Woman SCA 15 19 Not SCA 56 1 Using (1 = 0.05 indicates whether there is a relationship between the gender of students and interests in working in government agencies
