Interpreting technology: The following display from the TI-84 Plus calculator presents the least-squares regression line for predicting the price of a certain stock y from the prime interest rate in percent x. LinReg =y+abx =a2.43958189 =b0.35528112 =r20.3718412098 =r0.60978784 Write the equation of the least-squares regression line.

Stock price=2.43958189+0.35528112 Interest rate

Step-by-step explanation:

The structure of linear regression equation is

y=a+bx

Where a=intercept,

b=slope,

y=dependent variable/response variable,

and

x=independent variable/explanatory variable.

The given information shows that

y=dependent variable/response variable=stock price,

and

x=independent variable/explanatory variable=interest rate.

So, the regression equation that is to be estimated is

stock price=a+b interest rate.

The output shows that a=2.43958189 and b=0.35528112.

Thus, the estimated equation of the least-squares regression line is

Stock price=2.43958189+0.35528112 Interest rate
