- Does Table 1 represent a linear function? If so, finda linear equation that models the data.arrow_forwardUse an equation to express a least-squares regression line. Interpret each term in the equation.arrow_forwardWeight (pounds) A random sample of 17 vehicles was chosen and the weights, in pounds, and gas mileage, in miles per gallon, were recorded. A scatterplot of the data and a linear regression model are shown in the figure above. The model predicts that a 2,200-pound vehicle will have a gas mileage of 31 miles per gallon and a 3,500-pound vehicle will have a gas mileage of 18 miles per gallon. What does the model predict for the gas mileage of a 4,000-pound vehicle? O 23 miles per gallon O 15 miles per gallon O 13 miles per gallon O 10 miles per gallon Gas Mileage (miles per gallon)arrow_forward

- The table below shows the average weekly wages (in dollars) for state government employees and federal government employees for 10 years, construct and interpret a 98% prediction interval for the average weekly wages of federal government employees when the average weekly wages of state government employees is $888 the equation of the regression line is y= 1.453x-47.386. Wages(state), X | 739|760|784|822|898|921|937|954|965| Wages (federal), Y |1,036|1,054|1,105|1,136|1,192|1,253|1,266|1,327|1,400|arrow_forwardRegression refers to a dependent variable (Y) and an independent variable (X). Explain the meaning of dependent and independent variable.arrow_forwardWhere is the quadratic model for the data?arrow_forward
- Biochemical oxygen demand (BOD) measures organic pollutants in water by measuring the amount of oxygen consumed by microorganisms that break down these compounds. BOD is hard to measure accurately. Total organic carbon (TOC) is easy to measure, so it is common to measure TOC and use regression to predict BOD. A typical regression equation for water entering a municipal treatment plant is BOD = -55.47 + 1.505 TOC Both BOD and TOC are measured in milligrams per liter of water. (a) What does the slope of this line say about the relationship between BOD and TOC? TOC rises (falls) by 1.505 mg/l for every 55.47 mg/l increase (decrease) in BOD BOD rises (falls) by 55.47 mg/l for every 1 mg/l increase (decrease) in TOC TOC rises (falls) by 1.505 mg/l for every 1 mg/l increase (decrease) in BOD BOD rises (falls) by 1.505 mg/l for every 1 mg/l increase (decrease) in TOCarrow_forwardThe table below shows the average weekly wages (in dollars) for state government employees and federal government employees for 10 years. Construct and interpret a 99% prediction interval for the average weekly wages of federal government employees when the average weekly wages of state government employees is $925. The equation of the regression line isarrow_forwardGiven the data (1,2), (3,6) and (5,14). Use the method of least squares to calculate the estimated regression. coefficients.arrow_forward
