Hello pjjain, i have a couple of assignments for you to look at. Thanks! I also attached module 7 that you helped me with already
Homework Assignment #9Name: __________________________All calculations should be done in Word using Equation Editor and all charts and graphs shouldbe done in Excel.Use the output below to answer the following questions.A baseball analyst would like to develop a model to predict the number of wins during the 2014baseball season. The analyst collected several variables: Wins, ERA, Runs Scored, Hits andSaves from 27 professional baseball teams. The data is shows below.Regression StatisticsMultiple R0.9232Observations27ANOVAdfRegressionResidualTotalVariableInterceptERARunsScoredHitsSavesSSMSF??????469.348??746.297??????SignificanceF0.000145539Coefficient72.456-10.234StandardError14.4173.3201T value5.02573??P value0.000020.0007Lower95%??-17.1194Upper95%??-3.3480.0723-0.01742.2150.00860.011321.2188.40698????0.001230.04570.062340.05446-0.04087??0.090130.00607??1)Fill in the tables with the missing values? (You should have 14 different values you need to find)2)What is the coefficient of determination?3)What is the adjusted r2?4)What is the standard error of the estimated regression line?5)What is the estimated regression equation?6)Use the estimated regression equation to predict Wins when ERA 6.6, Runs Score is 925, HitsAllowed is 1523 and Saves are 33.7)Calculate the residual for the observed described in number 6), if the original Wins for thatobservation were 109.8)What is the hypothesis scenario?9)Is there evidence of a significant relationship between the OVERALL Wins and the independentvariables? Use alpha = .05. (State the p-value and the conclusion)10)Which of the independent variables are significant predictors of Wins? Which ones do you wantto include in your model? Use alpha = .05
