In the regression equation, Y=75.65+0.50X, the intercept isa.0.5b.75.65c.1d.Undeterminable

The intercept in linear regression represents:a.the strength of the relationship between x and yb.the expected x value when y is zeroc.the expected y value when x is zerod.a population parameter

In a simple regression analysis, the Y-intercept represents:A.The error term in the model.B.The estimated value of the dependent variable (Y) when X is zero.C.The slope of the regression line.D.The strength of the linear relationship between X and Y.

If the regression model is given as y= 63.3 + .51x , give an estimate of y when x = 25Group of answer choices68.770.576.0565.2

Adrian records the number of chirps per minute ( x ) that crickets make at different temperatures ( y ).He determines that the association is linear and that the line of best fit is 𝑦=15𝑥+50y= 51​ x+50.What is the interpretation of the slope and y-intercept of this equation?Click here for long descriptionA.The slope predicts a temperature increase of about 1° for every increase of 50 chirps per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 1551​ °.B.The slope predicts a temperature increase of about 1551​ ° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 50°.C.The slope predicts a temperature increase of about 50° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 0°.D.The chirping increases as the temperature goes down.
