A county real estate appraiser wants to develop a statistical model to predict the appraised value of houses in a section of the county called East Meadow. One of the many variables thought to be an important predictor of appraised value is the number of rooms in the house. Consequently, the appraiser decided to fit the linear regression model: E(y) = β0 + β1x, where y = appraised value of the house (in thousands of dollars) and x = number of rooms. Using data collected for a sample of n = 74 houses in East Meadow, the following result was obtained: = 74.80 + 19.72x
Which of the following statements concerning the deterministic model, E(y) = β0 + β1x is true?
Question 3 options:
All of these statements are true.
In theory, a plot of the mean appraised value E(y) against the number of rooms x for the entire population of houses in east Meadow would result in a straight line.
A plot of the predicted appraised values against the number of rooms x for the sample of houses in East Meadow would not result in a straight line.
In theory, if the appraised values y and number of rooms x for the entire population of houses in East Meadow were obtained and the (x, y) data points plotted, the points would fall in a straight line.
It is mentioned that, the appraiser decided to fit the linear regression model: E(y) = β0 + β1x, where y = appraised value of the house (in thousands of dollars) and x = number of rooms.
Using data collected for a sample of n = 74 houses in East Meadow,
the following result was obtained: = 74.80 + 19.72x which, is a straight line equation
As the sample taken from the population, showing the straight line plot between E(y) and x then it is expected that
In theory, a plot of the mean appraised value E(y) against the number of rooms x for the entire population of houses in east Meadow would result in a straight line.

A county real estate appraiser wants to develop a statistical model to predict the appraised value of houses in a section of the county called East Meadow. One of the many variables thought to be an important predictor of appraised value is the number of rooms in the house. Consequently, the appraiser decided to fit the simple linear regression model, y=β0+β1x, where y=appraised value of the house (in $thousands) and x=number of rooms. Using data collected for a sample of...

A real estate agent would like to know if the number of bedrooms in a house can be used to predict the selling price of the house. More specifically, he wants to know whether a larger number of bedrooms leads to a higher selling price. Records for 25 houses that recently sold in the area were selected at random, and data on the number of bedrooms (x) and the selling price y (in $000s) for each house were used to...
The CFO of the company would like to use the number of years employees have been with the company to predict the employees’ salaries. To that end, the CFO decided to fit the linear regression model E(y) = β0 + β1x, where Y = the salary of an employee (in thousands of dollars) and X = the years employed with the company. Using data collected for a sample of n = 35 employees of the company, the following result was...

13.76 You want to develop a model to predict the selling price of homes based on assessed value. A sample of 30 recently sold single-family houses in a small city is selected to study the relationship between selling price (in thousands of dollars) and assessed value (in thousands of dollars). The houses in the city were reassessed at full value one year prior to the study. The results are in House 1. (Hint: First, determine which are the independent and...
