The distribution of life spans for gas ovens (G) has a mean of 15.0 years and a standard deviation of 4.2 years. The distribution of life spans for electric ovens (E) a mean of 13.4 years and a standard deviation of 3.7 years. Both distributions are moderately skewed to the right. Suppose we select a simple random sample of 35 gas ovens and a second simple random sample of 40 electric ovens. What is the probability that the sample mean lifespan for the electric ovens is greater than the sample mean lifespan of the gas ovens?
