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

EXERCISE 36 Questions to be graded 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. * The F-value suggests that there is a significant difference between the results of the control and treatment groups. The P-value of 0.005 is < the alpha of 0.05. This suggest that the groups are significantly

The exercise provided a great sense of bad arguments and the various fallacies. The quiz gave examples of fallacious appeals such as questionable authority‚ common belief; two wrongs do not equal a right‚ common practice‚ wishful thinking and indirect consequences. Generally speaking the multiple choice answers were tricky as most of the choices were very similar in content and form. The trick to identifying the correct answer is found in previous reading and looking forward. Key words or the
