I until 2 Buntil S A professor would like to test the hypothesis that the average grade for a student taking a 10 AM statistics class is more than five points higher than the average grade from a student in an 8 AM statistics class. The following data shows the sample size and average grades for students in the two class times along with the population It is claimed that in a mobile game, Pokemon Go, less than 10% are active players. A standard deviations. sample of 400 players is examined and 50 are active players. 10 AM Sample mean 87.1 81. 4 Calculate the value of the test statistic. Sample size 32 30 Population standard deviation 3.2 A. -1.94 B. -1.51 Let Population 1 be defined as the 10 AM class and Population 2 as the 8 AM class. C. 1.67 D. 1.83 Specify the null and alternative hypotheses for the test. A. Ho: /1 - 12 = 0; HA: /1 - /2 # 0 B. Ho: (1 - /2 S 0; HA: /1 - H2 > 0 C. Ho: M1 - 12 2 5; HA: M1 - H2 5 2 y Determine the p-value based on the value of the test statistic. Calculate the value of the test statistic. A. 0.0262 B. 0.0655 A. 0.84 C. 0.9525 B. 0.95 D. 0.9664 C. 1.28 D. 1.47 S At 10% significance level, the decision is to_ A. reject Ho; it can be concluded that the average grade for a student taking a 10 AM statistics class is more than five points higher than the average grade from a student in an 8 AM statistics class B. reject Ho; it can be concluded that the average grade for a student taking a 10 AM statistics class is more than five points lesser than the average grade from a student in an 8 AM statistics class C. do not reject Ho; it cannot be concluded that the average grade for a student taking a 10 AM statistics class is more than five points higher than the average grade from a student in an 8 AM statistics class D. do not reject Ho; it cannot be concluded that the average grade for a student taking a 10 AM statistics class differs by five points from the average grade from a student in an 8 AM statistics class
