Amil zakat is investigating the effectiveness of transporting rice for distributed in the city of Bandung. For that they plan to buy a car carrier and determine that a new car will be purchased if there is evidence that performance new cars have a higher average effectiveness than those produced old car. The standard deviation for the old car carrying limit is 12 kilograms and for a new car is 7 kilograms. A sample of 150 sacks of rice transported by an old car shows a sample with an average of 75 kilograms, while the same sample of 150 sacks of rice transported by a new car showed an average of 82 kilograms. Using the 5% significance level, is can it be proven that the amil must buy a new car?
