Basics of regression A regression analysis is run. The sum of squares due to error(SSE)=985. The sum of squares (SST)=231.Find the value of R.(R>0) (Round your answer to 2 decimal places)

In the regression equation, what does the letter X represent? Multiple Choice The dependent variable The independent variable The Y-intercept The slope of the line

The percentage of the variation in the value of y this is explained by the lease squares regression line is Group of answer choices   ρ the slope of the regression line. the correlation coefficient. the coefficient of determination. the y-intercept of the regression line.   The data below shows the summary statistics for a regression analysis on car weight (in metric tons) and fuel consumption (in miles per gallon). b0=48.8b0=48.8  b1=−8.37b1=−8.37  r2=0.36r2=0.36    (Note that 0.362=0.13 and 0.36−−−−√=0.6)(Note that 0.362=0.13 and 0.36=0.6)        Choose the correct interpretation of the y-intercept of the line:

Regression was used to determine if the number of beers a person drinks predicts blood alcohol content (BAC) in a random sample of college students. The results are in the table below. Intercept Beers Coefficients Standard Error 0.013 0.002 -0.013 0.018 t Stat P-value -1.005 0.332 7.480 2.97E-06 Write out the answers to each of the following questions and upload a picture of yo a. Write out the prediction equation. b. Interpret the slope. c. What is the predicted value for BAC for someone who drank 3 beers? Show your work. d. If the number of beers equals 5 and the BAC equals 0.10, what is the residual? Show your work.

pls send me answer of both parts then i will rate you sure.
