Interpreting regression results 2. This is the result of a regression where goals is the dependent variable and minutes played is the explanatory variable. a. Write out the simple linear regression equation that predicts goals based on time played using the output displayed here. If the average soccer player played one additional game (90 minutes), how many additional goals would you predict them to have scored? b. Call: 1m(formula goalstimeplayed, data -data) Residuals: Min 1Q Median 3Q Max 5.0572-1.6294 -0.3651...

I am needing help understanding this practice multiple regression analysis. Any help is appreciated! The output below is from a multiple regression analysis on the variable "Location". The variable "Location" is a dummy variable, where 0 = urban and 1 = rural. Please refer to the output below for parts a and b. a) If the analysis were correct, what would be your interpretation of the results (please be thorough)? b) What is wrong with the analysis? Which mistakes were...

What do the unstandardized coefficients shown in the below Coefficients table mean? Create your regression formula, i.e., putting the values of coefficients from Model 4 into the regression equation. Finally, apply your model for estimation: what is the estimated percentage of weekly income at S650 or less (% Income less $650/wk) for all SA3 communities in Metropolitan Melbourne in 2016 if the proportion of the residents born in China (% China-bom of Overseas-born) is 8.2%, the proportion of dwellings without...

a) What is the formula for the
estimated regression line?
b) Is the overall regression significant at a significance level
of 0.01? Hint: Perform an F test at a significance level of 0.01.
No work is required because all of the numbers can be obtained from
the computer output.
c) Which of the variables are linearly associated with the fungi
concentration assuming that the rest of the variables are in the
model? You may assume a significance level of 0.01....
