As v Question 8 of 27 This test: 75 point(s) possible Assessed Value Taxes This question: 25 point(s) possible Submit test 427.9 5009 m 367.3 3698 311.5 3695 377.3 5202 A researcher wants to develop a model to predict the taxes of houses, based on assessed value. A sample of 30 single-family houses listed for sale in a 447.6 1466 V particular region is selected. The taxes (in $) and the assessed value of the houses (in $thousands) are recorded, with the accompanying results. Complete 509.1 5181 parts (a) through (9) below. 343.1 3411 Click the icon to view the house data. 343.7 3923 434.9 4397 328.9 3268 292.2 2876 397.2 4007 c. Use the prediction line developed in (a) to predict the mean taxes for a house whose assessed value is $375,000. 392.4 4729 481.9 4883 480.7 4890 Y , = $ 390.3 3913 (Round to the nearest dollar as needed.) 373.4 3729 312.8 3099 d. Determine the coefficient of determination, r, and interpret its meaning in this problem. Select the correct choice below and fill in the answer box within your 342.1 3639 304.7 3541 choice. 275.4 3431 (Round to three decimal places as needed.) 458.6 4633 A. The coefficient of determination is r2 = . This value is the probability that the slope of the regression line is statistically significant. 232.9 4010 448.1 4564 505.6 5951 OB. The coefficient of determination is r2 = . This value is the proportion of variation in taxes that is explained by the variation in assessed value. 307.7 3045 351.4 3501 OC. The coefficient of determination is = . This value is the proportion of variation in assessed value that is explained by the variation in taxes. 413.2 3381 276.7 2703 O D. The coefficient of determination is r2 = .This value is the probability that the correlation between the variables is statistically significant. 337.5 4311 e. Perform a residual analysis on the results and evaluate the regression assumptions. The residual plot shows and spread. Plotting the residuals in collection order Time Remaining: 01:07:45 Next
