suppose that for sexually active male drosophila fruit flies in a particular genetic lab, the mean lifespan is 38.9 days, with a standard deviation of 12.0 days. When she experimentally removed all female from a simple random sample of 24 drosophila male flies in this lab, a researcher found that the 24 sexually inactive males had a mean lifespan of 62.5 days, with a standard deviation of 14.1 days. Answer the questions below about the experiment about testing whether sexually activity significantly affects the mean lifespan of Drosophila males. a. in this experiment what was the independent variable? b. in this experiment what was the dependent variable? c. For this experiment what was the null hypothesis and what was the alternative hypotheses. Use the appropriate symbols to represent the hypotheses.
