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 _<_ pvalue
b. 0.05 S pvalue < 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 (4243): 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
