Randomized samples are taken from three groups of students in three statistics courses from three different programs: an on-ground course (GROUND), an online course (ONLINE) and a hybrid course (HYBRID). Scores on a standardized test are collected for each class which are presented below: GROUND ONLINE HYBRID 124.36 117.70 88.47 100.14 111.33 83.44 112.23 115.92 110.56 119.35 117.12 102.37 128.63 116.14 110.20 88.37 112.37 107.01 107.88 99.82 119.34 123.06 110.51 125.64 126.63 123.98 122.26 91.03 126.48 89.85 99.79 118.68 124.76 109.34 95.52 95.73 118.09 110.09 126.69 104.85 123.74 101.84 118.21 109.65 77.89 105.54 105.52 104.17 108.62 98.48 90.84 99.01 115.87 120.30 116.15 110.91 108.30 131.69 80.99 119.25 87.89 A single instructor teaches all three courses and is interested in determining whether performances are affected by the course type. But first, she would like to know learn as much about each course as she can. Using an alpha level of 0.01, ascertain the performance of the sample data for insight on the courses. Perform the t test on the difference of means for each of the pair of means for the courses. Are they all equal? A1. A2. B1. B2. C1. C2. D. == For Ho: GROUND = ONLINE, what is the result given the population standard deviations being unknown and unequal? P-VALUE = (Write in the value) (Write in the value) What is the result given the population standard deviations are equal? P-VALUE = For Ho: GROUND = HYBRID, what is the result given the population standard deviations being unknown and unequal? P-VALUE= (Write in the value) (Write in the value) What is the result given the population standard deviations are equal? P-VALUE = For Ho: ONLINE =HYBRID, what is the result given the population standard deviations being unknown and unequal? P-VALUE = (Write in the value) (Write in the value) What is the result given the population standard deviations are equal? P-VALUE= Which pairs have tested showing statistically different means? i. GROUND and ONLINE ii. GROUND and HYBRID iii. ONLINE and HYBRID iv. All have tested equal
