Sketch a normal curve with the following parameters. (a) mean of 15 and standard deviation of 2 (b) mean of 15 and standard deviation of 3 (c) mean of 12 and standard deviation of 2 (d) mean of 12 and standard deviation of 3 (e) Consider two normal curves. If the first one has a larger mean than the second one, must it have a larger standard deviation as well? Explain your answer. Yes. The values of μ and σ are independent.No. The values of μ and σ are independent.No. As μ increases, σ will decrease.Yes. As μ increases, σ must also increase.
