Transcribed Image Text:3. A farmer is interested to know if the two brands of fertilizers have mean weight differences in the potatoes. He created two groups and assigned a brand of fertilizer to each group. There are 59 samples of potatoes on both fertilizer A and B with a standard deviation of 0.75 gram and 0.65 gram respectively. Using fertilizer A, the potatoes have an average weight of 0.75 grams while fertilizer B has 0.65 gram. Test the hypothesis at a = 0.05.
