You are interested in predicting the length of someone's nose on the basis of the number of lies a person tells per day (the Pinocchio hypothesis). You collect data from 100 random individuals and find that the mean number of lies told is 12 by age 25 (age limit for sample). Mean nose length among participants is 5.2 cm (bridge to tip). Based on the data, the slope of the relationship is 0.49. What is the y-intercept? (round to two decimal places).

Absenteeism: Absenteeism can be a serious employment problem. It is estimated that absenteeism reduces potential output by more than 10%. Two economists launched a research project to learn more about the problem. They randomly selected 100 organizations to participate in a 1-year study. For each organization, they recorded the average number of days absent per employee and several variables thought to affect absenteeism. Analyses and slope provided below. Use these analyses and the slope coefficient for U/M Rel to describe how the relationship between the union and the management affects absenteeism. Use these analyses and the slope coefficient for Av Shift to describe how organizations who offer shift work compare to those that do not.
find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. In each case, there is sujficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. Altitude and Temperature Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded by the author during Delta Flight 1053 from New Orleans to Atlanta. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet).
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.
