Data for a sample of 25 apartments in a particular neighborhood are provided in the worksheet Apartments in the Excel workbook MATH302_Final.xls. At the .05 level of significance determine if the correlation between rental cost and apartment size is significant. A. No, there is not a statistically significant linear relationship between monthly rental cost and apartment size, because the sample correlation coefficient is less than .95. B. Yes, there is a statistically significant linear relationship between monthly rental cost and apartment size, because the p-value for this test is less than .0001. C. Yes, there is a statistically significant linear relationship between monthly rental cost and apartment size, because the t-test value, 7.74, is greater than the critical value 1.96. D. Yes, there is a statistically significant linear relationship between monthly rental cost and apartment size, because the sample correlation coefficient 0.85 exceeds 0.50. 8. Given the same data referenced in problem 7 above, find the estimated regression equation which can be used to estimate the monthly rent for apartments in this neighborhood using size as the predictor variable. A. B. C. D. 9. Given the same data referenced in problem 7 above, find a point estimate for the average monthly rent for apartments having 1,000 square feet of space. Place your answer, rounded to the nearest whole dollar, in the blank. When entering your answer into the Final Exam Shell do not use any labels or symbols. Simply provide the numerical value. For example, 123 would be a legitimate entry. ________________
