Is the coefficient for the slope statisticallysignificant?c) A student comments that because the P-value for theslope is very small, Midterm 2 is very well predicted from Midterm 1.

A researcher measured the height (in feet) and volume of usable lumber (in cubic feet) of 32 cherry trees. The goal is to determine if the volume of usable lumber can be estimated from the height of a tree. The results are plotted below: 80 – 70- 60 - 50– 40 - 30 - 20 - 10- 60 65 70 75 80 85 90 Height The interpretation of this scatter plot is O There is a quite linear, positive and strong relationship between height and volume. O There is a positive and weak relationship between height and volume. O There is a negative and strong relationship between height and volume. There is a quite linear, positive and weak relationship between height and volume and there is an outlier.

Need help answering A, B and C. B) Perform the linear regression calculation and provide the linear regression equation that describes the relationship between Y (number of air conditioning units sold) and X (outside temperature in degrees Fahrenheit. Calculate: Coefficient of determination (r2) and the coefficient of correlation (r).  SST, SSE and SSR for this linear regression.  Estimate for the variance (σ2) and the standard deviation for the linear regression model you have developed. C) Using the linear regression equation that you developed in topic (b), calculate the estimated sales for a day that will reach 72 degrees F and for a day that will reach 94 F and for both temperature levels calculate the error “e” when comparing the estimated value against the actual data provided. At which of the two temperatures, is your model more accurate? Justify.
