Suppose that as an investor in the stock market, you're looking for a stock that's going tomove in tandem with the overall market. You compute the returns for a stock you'relooking at, and run a regression against a broad market index, obtaining the followingregression output:SUMMARY OUTPUTMultiple RR SquareAdjusted R SquareStandard ErrorObservationsRegression StatisticsANOVARegressionResidualTotalInterceptBroad Market Index47.218.0210.9980.9960.9960.19010.998df189SS0.1310.98880.5410.28980.828MSLLFCoefficients Standard Errort StatP-value.014 0.3403410.1300.021 47.218 4.39E-11What is the test statistic corresponding to the claim that there is a significant correlation?o enter 3 decimal placesSignificance FWhat is the test statistic for the overall validity of the model?enter 3 decimal placesWhat is the best estimate for the pooled variance?xenter 3 decimal placesLower 95% Upper 95%0.0300.1670.9401.036

A sample of n = 120 scores were presented using the Tenacity (authority) scores to the following predictors: age gender, SES, tone of voice, and clothing. Using a two-tailed test at the 0.05 level of significance, a multiple regression analysis was computed: 1. tenacity and age (pvalue = 0.043); 2. tenacity and gender (pvalue = 0.102); 3. tenacity and SES (pvalue = 0.40); Using the pvalue, provide your DECISION, whether: Accept Ho or Reject Ho, Accept Ha
A research department of an American automobile company wants to develop a model topredict gasoline mileage (measured in MPG) of the company’s vehicles by using theirhorsepower and weights (measured in pounds). To do this, it took a random sample of 50vehicles to perform a regression analysis as follows: SUMMARYOUTPUTRegression StatisticsMultiple R 0.865689R Square 0.749417Adjusted RSquare 0.738754Standard Error 4.176602Observations 50ANOVAdf SS MS FRegression a 2451.973702 1225.987 dResidual b 819.8680976 cTotal 49 3271.8418CoefficientsStandardError t StatIntercept 58.15708 2.658248208 21.87797Horsepower -0.11753 0.032643428 -3.60028Weight -0.00687 0.001401173 -4.90349(a) State the multiple regression equation.

Which of the following scatterplots provides evidence that the condition of equal variance for inference for the slope of a regression line has not been met?
Consider a regression analysis with n = 47 and three potential independent variables. Suppose that one of the independent variables has a correlation of 0.95 with the dependent variable. Does this imply that this independent variable will have a very large Student’s t statistic in the regression analysis with all three predictor variables?
