Scientific mass appraisal is a technique in which linear regression methods applied to the problem of property valuation. The objective in the Scientific Mass Appraisal is to predict the sale price of a home from selected characteristics of the building and taxes paid on the buildingTwenty four observations were obtained. The list of variables is also given.Answer the following questions, in each case justifying your answer by appropriate analyses.(a) In a fitted regression model that relates the sale price to taxes and building characteristics, would you include all the variables?(b) A veteran real estate agent has suggested that local taxes, number of rooms and age of the house would adequately describe the sale price . Do you agree ?(c) A real estate expert who who was brought into the project reasoned as follows:“ The selling price of a home is determined by its desirability and this is certainly a function of the physical characteristic of the building. This overall assessment is…

The distinctions between the simple and multiple linear regression model are in the following except: Number of regressors in the study Number of assumptions about the model Number of response variables in the model Number of degree of freedom of Residual Sum of Squares

Please help me understand this problem more in depth. A researcher is investigating possible explanations for deaths in traffic accidents. He examined data from 2000 for each of the 52 cities randomly selected in the US. The data included information on the following variables: Deaths: The number of deaths in traffic accidents per city Income: The median income per city As part of his study, he ran the following simple linear regression model attached in photo.  Question: Based on the above results, the researcher tested the hypotheses: Ho: B1=0 versus B1 not equal to 0, versus using T test. What do we know about the test statistic of the test? Based on the approximate p-value, what's the conclusion?

What are the assumptions of a multiple linear regression model? What would you do to look for violations of the multiple linear regression model assumptions

(a) Explain the requirements of the data for which multiple linear regression can be applied. (b) Take a use case from your work environment or elsewhere, identify one dependent variable and at least five independent variables (At least one of it needs to be a categorical variable) for which you would like to fit a multiple regression model (c) Explain some of the key interpretations you would be doing based on the output of the generated linear regression model.

The ACME golf ball company believes they have created a golf ball that will travel 25 yards further than the top brand--Brand X. To test this, they recruited 40 professional golfers and had each golfer drive the ACME ball and measure the distance, then drive Brand X's ball and measure the distance. Which hypothesis test is most appropriate to use in this scenario? ● Two-sample t-test Paired t-test Two proportions test Multiple linear regression
