The following information corresponds to Question 19 and 20.An airline company knows that it will need to purchase 5,000 metric tons of jet fuel in threemonths. It seeks protection against an upturn in prices using futures contracts. As there is nofutures contract on jet fuel, the company refers to heating oil instead. The company can hedgeusing heating oil futures contracts traded on NYME and the notional for one contract is 42,000gallons. The current price of jet fuel is $277/metric ton. The futures price of heating oil is$0.6903/gallon. Additionally, you are given the regression results below.Linear Regression Results for Airline Risk ManagementThe dependent variable (Y) is the quarterly return on jet fuel price, while the independent variable (X) is thequarterly return on the heating oil futures contract. The table below summarizes the results of a linear regressionY = a+BX+e, which covers estimates, standard errors, and other statistics. The numbers in the parenthesis denotethe standard error of the estimate. For instance, 0.007 denotes the estimated interceptâ = 0.007, whereas 0.0101below it corresponds to the standard error of this estimate.âCoxObservationsR²Adjusted R²Residual Std.

2.2 In a population, the correlation coefficient between family income and child IQ is 0.30. The mean family income was $60,000. The standard deviation in income is $20,000. IQ is measured on a scale such that the mean is 100, and the standard deviation is 15. (a) Using this information, predict the expected IQ of a child whose family income is $70,000 (b) How reliable do you expect this prediction to be? Why? (your answer should be a property of correlation, not an opinion about IQ) (c) The family income now rises-does the correlation predict that the child will have a higher IQ? Why?

A researcher wants to investigate the effects of environmental factors on IQ scores. For an initial study, she takes a sample of 400 people who grew up as the only child. She finds that 51.5% of them have an IQ score over 100. It is known that 50% of the general population has an IQ score exceeding 100. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of people with IQ scores over 100 in a random sample of 400 people. (b) Find the standard deviation of p. (c) Compute an approximation for P(p 20.515), which is the probability that there will be 51.5% or more individuals with IQ scores over 100 in a random sample of 400. Round your answer to four decimal places.

5. Bone mineral density (BMD) is a measure of bone strength. It is defined as the ratio of bone mass to the cross- sectional area of the bone that is scanned, and it is expressed in units of grams per square centimeter (g/cm²). Recent studies suggest that peak BMD in women is achieved between ages 15 and 40, and BMD declines after age 45. Decreased BMD is associated with increased risk of bone fracture. In a recent study, the impact of regular physical exercise on women in differing stages of BMD development was examined. A simple random sample of 59 women between the ages of 41 and 45 and with no major health problems were enrolled in the study. The women were classified into one of the two following groups, based on their level of exercise activity. • Sedentary: minimal participation in physical exercise in the past three years (This group contained 31 women.) • Walkers: walk at an aerobic pace at least 135 minutes per week during the past three years (This group contained 28 women.)…
