A regression between foot length (response variable in cm) and height (explanatory variable in inches) for 42 students resulted in the following regression equation: y = 10.4 + 0.21x If a student happened to be extraordinarily tall (say, 10ft, just for the fun of it) and had a foot size of 25 cm, how might this affect the slope of the regression line?

When conducting a linear regression the _____ refers to how much variability in the outcome is explained by the predictor(s). R R2 Slope Intercept
In a multiple regression setting which of the following statements is NOT correct? Select one: a. The estimated slope coefficient for the explanatory variable x1 represents how much the outcome variable changes when x1 increases by one unit and all other variables remain the same. b. Suppose you are interested in the relationship between food consumption and level of household income. Even though your primary interest is in the consumption-income relationship it is good practice to add in other explanatory variables such as household size in order to avoid problems of confoundment. c. As you add more explanatory variables to a multiple regression model you expect the standard error of the estimate to increase. d. With a large enough sample you can treat the estimated regression coefficients as if they are normally distributed irrespective of the underlying distribution of the error term.

Consider the insights derived from plot 1. Which of the following statements accurately reflects the data? Please select all that apply. Group of answer choices Institutions with ‘Above Average Expenditure’ tend to have a higher mean Out-of-State Tuition compared to those with ‘Below Average Expenditure’. If we were to fit a simple linear regression model to the data, the slope of the regression line would be positive. There is a negative correlation between the Student-Faculty Ratio and Out-of-State Tuition. The correlation between Student-Faculty Ratio and Expenditure Category is positive. The correlation between Out-of-State Tuition and Expenditure Category is negative.

Data were collected on monthly sales revenues (in $1,000s) and monthly advertising expenditures ($100s) for a sample of drug stores. The regression line relating revenues (Y) to advertising expenditure (X) is estimated to be y=−48.3+9.00x. What is the correct interpretation of the slope?
In a simple linear regression you are told that the estimate of the slope coefficient was 0.9 and that the "t-statistic" for testing whether the slope parameter was unity or not was -3.6. What is the estimated standard error for the estimated slope coefficient?(The answer should be correct to two decimal places.)
