The military often uses high-density metals in munitions because these metals are better able to penetrate armor. Magness (1994) conducted an obserational study of seven different high-density metals in which he measured the Rockwell hardness (the regressor) and the Young's Modulus (the response) for a single specimen for each metal. The Young's Modulus is the ratio of simple tension stress to the resulting strain parallel to the tension. Normally, we expect Young's modulus to increase as the Rockwell hardness increases.

Construct a scatterplot, calculate and interpret the correlation coefficient, and calculate the linear regression equation. Show all work for calculations!

It is important that face masks used by firefighters be able to withstand high temperatures because firefighters commonly work in temperatures of 200–500°F. In a test of one type of mask, 11 of 55 masks had lenses pop out at 250°. Construct a 90% upper confidence bound for the true proportion of masks of this type whose lenses would pop out at 250°. (a) Answer the question as given except find the 90% confidence interval estimate, not the 90% upper...

.Governments often claim that they impose high taxes on cigarettes because smoking is bad for your health. They claim that the high taxes are intended to discourage your consumption. Use your understanding of the elasticity of demand to dispute this claim, assuming that cigarettes have a very inelastic demand. Illustrate with a graph. Hint: Very inelastic is not the same as inelastic or perfectly inelastic.

Forestland Insurance Company underwrites insurance for properties in high density forest areas. It uses the estimate that the probability of a major forest fire destroying a home in any one year is 0.000043. If a homeowner takes a 30-year mortgage on a recently purchased property, what is the likelihood that the owner will experience at least one major forest fire during the mortgage period?
