Home prices Many variables have an impact on deter-mining the price of a house. A few of these are Size of the house (square feet), Lotsize, and number of Bathrooms.Information for a random sample of homes for sale inthe Statesboro, Georgia, area was obtained from theInternet. Regression output modeling the Asking Pricewith Square Footage and number of Bathrooms gave thefollowing result:Dependent Variable is Asking Prices = 67013 R-Sq = 71.1, R-Sq (adj) = 64.6,Predictor Coeff SE(Coeff) t-Ratio P-ValueIntercept -152037 85619 -1.78 0.110Baths 9530 40826 0.23 0.821Sq ft 139.87 46.67 3.00 0.015Analysis of VarianceSource DF SS MS F-Ratio P-ValueRegression 2 99303550067 49651775033 11.06 0.004Residual 9 40416679100 4490742122Total 11 1.39720E+11a) Write the regression equation.b) How much of the variation in home asking prices isaccounted for by the model?c) Explain in context what the coefficient of SquareFootage means.d) The owner of a construction firm, upon seeing this model, objects…

Event Mean StdDevHigh Jump 2.148 0.1939Long Jump 8.05 0.5136Correlation = 0.9125 a) Write the equation of the line of regression for esti-mating High Jump from Long Jump. b) Interpret the slope of the line.c) In a year when the long jump is 8.9 m, what high jumpwould you predict?d) Why can’t you use this line to estimate the longjump for a year when you know the high jump was2.25 m?e) Write the equation of the line you need to make thatprediction.
(Q.4) Mastery Assess It 3 - Question is in the photo privided below.
Regression and correlation analysis both describe the strength of linear relationships between variables. Consider the concepts of education and income. Many people would say these two variables are related in a linear fashion. As education increases, income usually increases (although not necessarily at the same rate). Can you think of two variables that are related in such a way that their relationship changes over their range of possible values (i.e., in a curvilinear fashion)? How would you analyze the relationship between two such variables?
