Extracted text: 1. Fill in the blank: For these data, distances from the beach that are greater than the mean of the distances from the beach tend to be paired with house prices that are Choose one the mean of the house prices. 2. According to the regression equation, for an increase of one mile in distance from the beach, there is a corresponding decrease of how many thousand dollars in house price? 3. From the regression equation, what is the predicted house price (in thousands of dollars) when the distance (in miles) from the beach is 10.0 miles? (Round your answer to at least one decimal place.) 4. What was the observed house price (in thousands of dollars) when the distance (in miles) from the beach was 10.0 miles?


Extracted text: With the aim of predicting the selling price of a house in Newburg Park, Florida, from the distance between the house and the beach, we might examine a regression equation relating the two variables. In the table below, the distance from the beach (x, in miles) and selling price (y, in thousands of dollars) for each of a sample of fifteen homes sold in Newburg Park in the past year are given. The least-squares regression equation relating the two variables is î-310.94 – 6.27x. The line having this equation is plotted in Figure 1. Selling price, y (in thousands of dollars) Distance from the beach, x (in miles) 8.6 290.7 12.8 198.8 10.0 230.7 350 7.6 272.4 3.6 261.5 300 10.4 274.8 12.5 267.2 250 15.1 183.6 18.8 225.6 200 7.6 244.0 4.3 314.0 150 8.2 220.8 6.1 311.1 12.0 234.1 Figure 1 10.6 205.8 Send data to Excel Based on the above information, answer the following: 1. Fill in the blank: For these data, distances from the beach that are greater than the mean of the distances from the beach tend to be paired with house prices that are Choose one the mean of the house prices. 2. According to the regression equation, for an increase of one mile in distance from the beach, there is a corresponding decrease of how many thousand dollars in house price? 3. From the regression equation, what is the predicted house price (in thousands of dollars) when the distance (in miles) from the beach is U 10.0 miles? (Round your answer to at least one decimal place.) 4. What was the observed house price (in thousands of dollars) when In the distance (in miles) from the beach was 10.0 miles?
