Chapter 1.3, Problem 17E

Freezing temperature. Ethylene glycol and propylene glycol are liquids used in antifreeze and deicing solutions. Ethylene glycol is listed as a hazardous chemical by the Environmental Protection Agency, while propylene glycol is generally regarded as safe. Table 11 lists the freezing temperature for various concentrations (as a percentage of total weight) of each chemical in a solution used to deice airplanes. A linear regression model for the ethylene glycol data in Table 11 is

E = 0.55 T + 31

where E is the percentage of ethylene glycol in the deicing solution and T is the temperature at which the solution freezes.

Chapter 1.3, Problem 17E, Freezing temperature. Ethylene glycol and propylene glycol are liquids used in antifreeze and

(A) Draw a scatter plot of the data and a graph of the model on the same axes.

(B) Use the model to estimate the freezing temperature to the nearest degree of a solution that

is 30% ethylene glycol.

(C) Use the model to estimate the percentage of ethylene glycol in a solution that freezes at

15°F.

We have data on Lung Capacity of persons and we wish to build a multiple linear regression model that predicts Lung Capacity based on the predictors Age and Smoking Status. Age is a numeric variable whereas Smoke is a categorical variable (0 if non-smoker, 1 if smoker). Here is the partial result from STATISTICA. b* Std.Err. of b* Std.Err. N=725 of b Intercept Age Smoke 0.835543 -0.075120 1.085725 0.555396 0.182989 0.014378 0.021631 0.021631 -0.648588 0.186761 Which of the following statements is absolutely false? A. The expected lung capacity of a smoker is expected to be 0.648588 lower than that of a non-smoker. B. The predictor variables Age and Smoker both contribute significantly to the model. C. For every one year that a person gets older, the lung capacity is expected to increase by 0.555396 units, holding smoker status constant. D. For every one unit increase in smoker status, lung capacity is expected to decrease by 0.648588 units, holding age constant.
A study was done in diesel-powered light-duty pickup truck to see if humidity, air temperature, and barometric pressure influence emission of nitrous oxide (in ppm). Emission measurements were taken at different times, with varying experimental conditions. a. Fit the multiple linear regression model. b. Estimate the amount of nitrous oxide emitted for the conditions where humidity is 50%, temperature is 76 deg F, and barometric pressure is 29.30. Nitrous Humidity, Temp., Pressure.

The production of wine is a​ multibillion-dollar worldwide industry. In an attempt to develop a model of wine quality as judged by wine​ experts, data was collected from red wine variants of a certain type of wine. A sample of 12 wines is given. Develop a simple linear regression model to predict wine​ quality, measured on a scale from 0​ (very bad) to 10​ (excellent), based on alcohol content​ (%).    b. For these​ data, b0=4.4 and b1=0.2. Interpret the meaning of the​ slope, b1​, in this problem. Choose the correct answer below.     A. The​ slope, b1​, implies that for each increase of 1 wine quality​ rating, the alcohol content is expected to increase by the value of b1​, in percentages.   B. The​ slope, b1​, implies that the alcohol content is equal to the value of b1​,in percentages.   C. The​ slope, b1​, implies that for each increase of alcohol percentage of​ 1.0, the wine quality rating is expected to increase by the value of b1.   D. The​ slope, b1​, implies that…
