Given the regression line y=-1.32+2.342xy = − 1.32 + 2.342 x , where the independent variable is number of dollars ($) invested and the dependent variable is the time (hours) spend working. a) What is the y-intercept of the regression line and interpret what it means? b) If you spent $20 in an investment, how many hours did you work?
a) y- intercept = -1.32
Interpretation : If the number of dollars invested is $0, then we expect the number of hours spend in working is -1.32 hours
b) if number of dollars invested = $20
No. of hours spend = -1.32 + 2.342*20
Number of hours spend = 45.52 hrs

The equation of the regression line between two variables x (independent variable) and y (dependent variable) is given by y-hat = -3x + 2; and the correlation coefficient is r = -.95. The possible x-values range from 1 to 10. Which of the following statements are correct? I. The variable y is strongly positive correlated to the variable x. II. The variable y is strongly negative correlated to the variable x. III. If x = 5, one would predict that...
Suppose you were presented with the following prediction regression equation: Yhat = 30,000 + 2,000 (X) where the dependent variable is annual salary and the independent variable is years on the job. Interpret the value of the y-intercept (i.e., constant) and the value of the slope. Be as thorough as possible in your answer!
Question 15 1 pts In a simple regression analysis (where y is a dependent and x an independent variable), if the y intercept is zero, then O the slope must be negative. o the slope can be positive, or zero, or negative. O there is no relationship between x and y. o the slope must be positive.
In a simple linear regression study between two variables x ( the independent variable) and y (the dependent variable), a random large sample is collected and the coefficient of correlation r = −.98 is calculated. A)Which of the following conclusion may be made? Group of answer choices x and y are almost perfectly correlated, and y increases as x is increased. x and y are almost perfectly correlated, and y decreases as x is increased. x and y are moderately...
