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?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
