2. A company is trying to decide which of the two types of tires to buy for their trucks. They would like to adopt brand C unless there is some evidence that brand D is better. An experiment was conducted where 16 tires from each brand were used. The tires were run under similar conditions until they wore out. The results are: Brand C: X, = 40,000 kms = 5,400 kms %3D Brand D: X, = 38,000 kms S2 = 3,200 kms What conclusion can be drawn? 3. Two types of rice varieties are being considered for yield and a comparison is needed. Thirty hectares were planted with the rice varieties exposed to fairly uniform growing conditions. The results are tabulated below: Variety A Variety B Average yield 80 sacks/hectare 35 sacks/hectare 12.1 Sample variance At .05 significance level, can we conclude that variety A is the better type? 5.9
