General Normal Distributions N(,)

1. Areas under a Normal Distribution. On the normal distribution N (20, 0.4), compute P(x20.8) Sketch a picture that captures the computation you are asked to do. Label the normal distribution with its mean and standard deviation.
2. Areas under a Normal Distribution. On the normal distribution N(10,40), compute P(5x5) . Sketch a picture that captures the computation you are asked to do. Label the normal distribution with its mean and standard deviation.
3. Boundaries under a Normal Distribution. Find the Xlower boundand Xupper bound that captures the middle 70% of the data in the normal distribution N(50,5). Sketch a picture that captures the computation you are asked to do. Label the normal distribution with its mean and standard deviation.
