Unformatted text preview: 41. Assume that the test statistic calculated above is 1.500. In which range does'the p—Value for the test lie? 250.01 = 2.326 20025 = 1.960 20,050 = 1.645 20.100 : 1.282 a. 0.10 _<_ p-value b. 0.05 S p-value < 0.10 c. 0.025 S p—value < 0.05 d. 0.01 S p—value < 0.025 e. p—value < 0.01 Use the following information to answer the next 2 questions (42-43): In an agricultural experiment, two expensive high—yield varieties of corn are to be tested and yield improvements are to be measured. The experiment is arranged so that each variety is planted side by side in seven pairs of plots. Data is collected on yield increases obtained for these two varieties. Variety A is population 1 and variety B is population 2. Plot Variety A Variety B—l 1 —| 12.6 10.5 2 9.2 8.1 3 6.4 6.2 4 9.8 10.1 5 15.3 12.2 6 16.1 14.0 7 12.3 10.1 42. What is the value of the 95% upper confidence limit for the difference in population means? 250.010 = 2.326 20025 = 1.960 20.05 = 1.645 20.10 = 1282 t0.010,6 = 3.143 150.0255 = 2.447 t0.05,6 = 1.943 120.105 = 1.440 150.010.12 = 2-681 750,025,12 = 2-179 to.05,12 = 1-782 730.10.12 = 1356 a. 2.624 b. 5.467 c. 2.501 d. 3.266 e. 2.392 1 7 253 ...
