U ran \"5] Calculate the least squares line. Put the equation in the form of: )7 = a + bx. (Round your answers to three decimal places.) i\"! = + x a Part (d) Find the correlation coefcient r. (Round your answer to four decimal places.) r = Is it signicant? Yes No a Part (e) Find the estimated height for 31 stories. (Use your equation from part (a). Round your answer to one decimal place.) ft Find the estimated height for 96 stories. (Use your equation from part (c). Round your answer to one decimal place.) ft 8 PM (1') Based on the above data, is there a linear relationship between the number of stories in tall buildings and the height of the buildings? Yes No a PM (9) Are there any outliers in the above data? If so, which point(s)? Yes, (57, 1050) is an outlier. Yes, (57, 1050) and (22, 401) are outliers. Yes, (22, 401) is an outlier. No, there are no outliers. a Part (h) What is the estimated height of a building with six stories? (Use your equation from part (c). Round your answer to one decimal place.) ft Does the least squares line give an accurate estimate of height? Explain why or why not. The estimate for the height of a six-story building does not make sense in this situation. The least squares regression line does not give an accurate estimate because the estimated height of a building with six stories is not within the range of y- values in the data. The least squares regression line does not give an accurate estimate because a six-story building is not within the range ofx-values in the data. The least squares regression line does give an accurate estimate because none of the buildings surveyed had six stories. a Part (i) Based on the least squares line, adding an extra story is predicted to add about how many feet to a building? (Round your answer to three decimal places.) ft 3 Part (I) What is the slope of the least squares (best-t) line? (Round your answer to three decimal places.) Interpret the slope. (Round your answer to three decimal places.) As the of the building increases by one unit, the of the building increases by - 4. [1/18 Points] DETAILS PREVIOUS ANSWERS ILLOWSKYINTROSTAT1 12.6.074.HW.
