Given the regression equation for the response of the reaction time in minutes to the exposure to a chemical level is Y = 2.3x – 1.8, what is the reaction to a level of 1.8?0.5 minutes2.34 minutes2.78 minutes2 minutesCorrectIf the response is 10, what is the predictor for Y = -3x + 5?-25-51.67-1.67CorrectA test score can be predicted from the number of hours spent studying with Y = 17x + 15. To achieve a perfect score of 100, the student should study hours.Correct5
The error of prediction is the observed value  the predicted value.SolutionThe correct answer is:minusThe  of the regression equation will have the same sign as the correlation of the regression.SolutionThe correct answer is:slopeThe y-intercept for a regression equation with the mean of y as 3.5, the mean of x as 2.8, and the slope of 2 is .SolutionThe correct answer is:-2.1
The error of prediction is  for an observed value of 5.6 and a prediction of 6.2.SolutionThe correct answer is:-0.6The slope of a regression equation with r = 0.85, standard deviation of the y values is 10, and the standard deviation of the x values is 12 is .CorrectFor the regression equation of Y = 2x – 3, the predicted value for the independent valueof 2.5 is .SolutionThe correct answer is:20.71
The bonus percentage for an employee in a company can be predicted by Y = 3.5x - 4.8, where x is the number of projects completed. If an employee received a 2.2% bonus, how many projects did the employee complete?32.912SolutionThe correct answer is:2R2 close to  indicated all variability has been accounted for in the calculations.SolutionThe correct answer is:1.0 values measure how strongly each predictor affects the criterion variable.SolutionThe correct answer is:
BetaMultiple regression estimates  or partial changes in the dependent variable.SolutionThe correct answer is:parameterIn multiple regression, multiple regression  replace the slope.SolutionThe correct answer is:coefficientsIn multiple regression, each observed value will contain more than one  value.SolutionThe correct answer is:predictor
The alternative hypothesis for ANOVA is that explanatory value is nonzero or predicts the dependent variable.CorrectGiven the first observation of (10, 5, 6, 2, 9), the criterion has a value of .SolutionThe correct answer is:9values measure how strongly each predictor affects the criterion variable.CorrectGiven the third observation of (5, 1, 4.5, 6, 9.1), there are  explanatory values.Solutionat least oneBeta
The correct answer is:4A coefficient of indicates no relationship.Correct linear regression cannot be used with more than two predictors.SolutionThe correct answer is:SimpleIn simple regression, a -dimensional line predicts the response values.SolutionThe correct answer is:two0
The formulas for multiple regression are typically .
