I need help please

The table below summarizes measurements taken for cancer patients prior to surgery The x values represent CAT scan measurements in mm (milimeters), while the y values are tumor mass in g (grams) (Statistics for Research 2nd ed., by Dowdy & Weardon, 1985, pp. 269 - 270, John Wiley & Sons) Note that this problem was in the homework but some of the homework data values have been removed so you may end with a different result this time. 18 28 20 24 16 19 24 23 20 25 16 21 22 23 27 18 (a) Find the amount of variation in the CAT scan measurements that can be explained by the tumor mass and write a short sentence that explains this result. (8 points) (b) At 6% significance, test the claim that the data exhibit linear correlation. Complete a hypothesis test between CAT scan measurements and tumor mass. Include every variable and all work that is important to make this decision. (20 points - 5,5,5,5) Describe what should be done to complete the requirement check Hypothesis statements Test statistic and p-value conclusion (c) Write the regression model for this data. Use correct notation. (6 points - 3, 3) (d) Make a best prediction for tumor mass for a CAT scan measurement of 25mm and then write a sentence that explains what this prediction tells us. (12 points - 5, 7) (e) Build a 92% confidence interval for the slope of the population model for the sample from page 2. Write down whether or not this interval includes zero then explain what containing zero (or not) indicates about the model. (8 points - 4, 4)
