Consider the following multiple regression modifyingabove price with caret equals 119.9 plus 0.484 bdr plus 22.4 bath plus 0.184 hsize plus 0.002 lsize plus 0.073 age minus 48.7 poor comma upper r overbar squared equals 0.73 comma ser equals 40.3 (24.4) (2.87) (8.26) (0.019) (0.00052) (0.343) (10.4) the numbers in parentheses below each estimated coefficient are the estimated standard errors. a detailed description of the variables used in the data set is available here suppose you wanted to test the hypothesis that bdr equals zero. that is, upper h 0 : bdr equals 0 vs upper h 1 : bdr not equals 0 report the t-statistic for this test. the t-statistic is 0.169 (round your response to three decimal places) is the coefficient on bdr statistically different from zero at the 5% significance level? a. yes. b. no. your answer is correct. typically five-bedroom houses sell for much more than two-bedroom houses. is this consistent with your previous answer and with the regression more generally? a. yes. your answer is correct. b. no. a homeowner purchases 1923 square feet from and adjacent lot. construct a 95% confidence interval for the change in the value of her house. the 95% confidence interval for the change in the value of the home is [ nothing, nothing] (round your response to two decimal places) enter your answer in the edit fields and then click check answer.

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.
