Researchers are trying to determine if there is a difference in the average lifespan of two species c fruit fly: Ceratitis capitata and Drosophila melanogaster. They measure the lifespans of two random samples of each species. The SRS of Cerati capitata was of size 105 and had an average lifespa of 51 days with a standard deviation of 7 days. The SRS of Drosophila melanogaster was of size 95 and ha an average lifespan of 48 days with a standard deviation of 6 days. Let μ₁ denote the mean lifespan of Ceratitis capitata and μ2 denote the mean lifespan of Drosop melanogaster. Compute the standard error of the statistic ₁
