Question
The content volume of 10 car lubricants from Brand X were recorded as in Table 1. Using a=0.01, test the hypothesis that the average content volume of the Brand X car lubricants is 10 liters. (а) Table 1: Content of containers for 10 car lubricants 10.3 9.9 10.2 10.1 | 9.7 | 9.9 9.8 10.3 10.0 10.4 Table 2 shows the birth weights (in Kgs) of babies born from fourteen (14) mothers who (b) taking a special vitamin supplement. In general, the standard deviation of the birth weights of babies is 0.44kg. At 95% significance level, test if the vitamin supplement has any effects on the standard deviation of the birth weight. Table 2: Birth weights of babies 3.70 4.31 3.73 4.33 3.33 2.58 4.47 3.55 4.66 3.68 3.02 4.09 2.36 3.35
