Since 1985, average mortgage interest rates have fluctuated from a low of 4.25% to a high of 14%. Is there a relationship between the amount of money people borrow and the interest rate that’s offered? Below is a scatterplot of Mortgage Loan Amounts in the US (in thousands of dollars) versus Interest Rate (in percent) at various times over the past 26 years. Which is the response variable and which is the explanatory variable? Suppose the linear regression model for this data is ? ̂ = 189.674 − 42.235?. Interpret the slope in the context of this scenario.
A vocational counselor uses the number of days without employment to predict her clients' feelings of self efficacy, measured on a scale of 1 to 5, with higher numbers meaning that clients feel more secure in their job related abilities. The slope of the regression line is –1.02. Which statement is the best interpretation for this finding? a. For every 1-point increase in self-efficacy, there is an associated decrease in the number of days of unemployment. b. For every additional day of unemployment, there is an associated decrease in self-efficacy of 1.02 points. c. The least number of days a person can be unemployed and still feel self-efficacious is 3.98 points d. The decrease in self-efficacy of 1.02 points is caused by each additional day of unemployment
