as the linear regression equation for 50), (6, 85). (10, 110)?

The line of best fit through a set of data is ý = 38.241 – 1.827r According to this equation, what is the predicted value of the dependent variable when the independent variable has value 20? y = Round to 1 decimal place.

To be accurate with the language of regression, we should state, “we regress y and x”.   a) True b) False

Given that the systolic blood pressure in the right arm is 90 mm Hg, the best systolic blood pressure in the left arm is how many mm Hg?

22. The equation P = 100(2.4)' models the number of bacteria, P, in a Petri dish / hours after the beginning of an experiment. Estimate the value of P after hours.

Assume in a regression, SSR = 2* SSE. What is the coefficient of determination (R-sq)? provide solution in decimal form

It has been hypothesized that overall academic success for first-year college students as measured by grade point average (GPA) is a function of IQ scores = X1, and hours spent studying each week = X2. Suppose the regression equation is: Y = -5.7 + 0.02X1 +0.5X2 1) What is the predicted GPA for a student with an IQ of 100 and 40 hours spent studying per week? 2)Will the independent variables be endogenous? State what it means by endogenous, and explain why that will be the case. 3) If you have a choice to change the variables or add/drop variables, what would be your set of independent variables, and explain why you chose those variables.

The line of best fit through a set of data is y = 13.661 – 3.451x According to this equation, what is the predicted value of the dependent variable when the independent variable has value 80? y = Round to 1 decimal place.

The quadratic regression equation shown below is for a sample of n=22. a. Predict Y for X1=3.     ​(Type an integer or a​ decimal.)
