Suppose that one chemical plant in a large corporation is accused of exceeding the established limits of toxins being released into the atmosphere. A decision is made to test whether or not the mean level of toxins exceeds the tolerance level μ0=100μ0=100 ppm (parts per million). How would the null and alternative hypotheses be set up given that the researcher is working for the corporation? How would those hypotheses change if the researcher is working for the Environmental Protection Agency (EPA)?

A professor gives a test worth 150 points and the resulting scores from herclass were found to be normally distributed with a mean of 97 and a standarddeviation of 20. She decides to apply a curve to the exam scores such that anA is +2σ or better, a B is between the +1σ and +2σ, a C is between the meanand +1σ, a D is between -1σ and the mean, and any score less than -1σ getsan F. What score would be needed to get an A? If there were 70 students inher class, by this curved distribution, how many student would she expect tohave an A? (Round to the nearest integer.)
