Exercise 9 1. A farmer wanted to find the relationship between the amount of fertilizer used and the yield of corn. He selected seven acres of his land on which he used different amounts of fertilizer to grow corn. The following table gives the amount of fertilizer (in pounds) used and the yield of corn (in bushels)for each of the seven acres. Fertilizer Used (x) 120 80 100 70 88 75 110 Yield of Corn(y) 138 112 129 96 119 104 134 a. Find the least squares regression line. a. Calculate r and r2

of water in the fluid that line the walls of the alveoli. Activity 5: Effect of Thoracic Cavity Puncture 1. What happened to the left lung when you clicked on the valve button? It deflated. 2. Why? Because the pressure in the left lung was 0 and the right lung changed rapidly‚ the air moved into the intrapleural space through the opening‚ causing intrapleural pressure. 3. What has happened to the “Total Flow” rate? It was reduced by ½. 4.

from Table VI‚ Appendix A‚ p. A-14‚ of your textbook Elementary Statistics. Use α = 0.05. Is there sufficient evidence to conclude that there is a linear correlation between the proportion of wins and the above difference? The null hypothesis is = 0 which shows the linear correlation is not significant. The alternative hypothesis where it is using the p-value: p-value =2p(t>test statistic) =2p(t>3.9833) =2[1-p(t 3.9833)] =2(0.005248) =0.010496 Clearly this shows that the p-value is less than
