Hi, I need a help. Thank you

1. A realtor wants to examine the relationship between the assessed value of a property (land and buildings) and the size of any house located on the property (measured in square feet). Below is a random sample of 6 properties in a subdivision that was built 5 years ago: Square Footage (in 100's) 21.7 22.5 23.0 23.0 26.5 29.0 Assessed Value (in $1,000's) 1,090 1,150 1,180 1,195 1,240 1,276 (a) Find the estimated regression line ? = a + bx to predict the assessed value based on the square footage of the house. [3 marks] ANSWER (2 decimal places): (b) What is the meaning of the slope? Interpret it using the words of the problem. [3 marks] (c) What is the meaning of the intercept? Interpret it using the words of the problem. [2 marks] (d) Predict the assessed value for a 2,400 square foot house in the subdivision. [2 marks] ANSWER: (e) Assessed values are used to calculate property taxes. A 2,400 square foot home in the subdivision is assessed at $1,275,000. The homeowner filed an appeal to have their assessment reduced. Are they justified in thinking the assessed value is too high? Explain. [2]
