Lesson Quizzes. Professor Velleman
broke the course into 25 lessons. We covered 19 of those
lessons. An online quiz was written for each lesson covered.
The student could take these quizzes anytime and any place. The only
requirement was an Internet connection. The student could take
each quiz up to 5 times. These quizzes counted ten percent of the
student's grade. No lesson quizzes were proctored and the students
were encouraged to get help. See Lesson Quiz 19A for an example.
-
Tests and Final Exam. Tests and
the final exam were delivered using WebCT. All these tests were
proctored. The tests were password protected and the password was
changed as soon as the students completed the test. The tests and
the final counted 90 percent of the student's grade. You may find
a list of lesson quizzes, tests and
surveys below.
-
Lecture Notes. Lecture
notes were provided for each lesson covered. Those notes may
be accessed from WebCT or my from my course site.
-
Communication. The bulletin board
was used to communicate with students. The students used the
bulletin board to post questions. Those questions were answered
using the bulletin board. All students could see the question and
response. The calendar was used to post the testing schedule.
Course Statistics
- Thirty-two students enrolled in the course
- Seventeen students were successful (C or better). All students who
took the final exam were successful.
- Thirteen students withdrew.
- One student received an I.
- Comparison with lecture class. All tests and lesson quizzes were
extremely similar. At times, the only difference in the questions was
the data used.
- Thirty-three students were enrolled in the lecture class.
Twenty-six were successful.
- The
class average for the online class was 83.2 and the class average
for the lecture class was 77.9. I wanted to determine whether
there was any significant difference between the final averages of
the two classes. I tested the alternate hypothesis Ha : monline ¹ mlecture
. Using the t-test, the p-value for this test was 0.38.
There was no significant difference between the two
classes. However, the results of this test must not be
given great weight. If students had been randomly assigned to
the two classes, the test could be given greater weight.

Question 1 (9 marks)
A very large high school wishes to know how it compares to the national average on the SAT Math. The national average is m = 600, the population standard deviation is s = 81. They believe that their students average is different from the national average. A SRS of 40 students is chosen and their average on the SAT Math is found to be 569. The null and alternative hypothesis are:
H0: m = 600
Ha: m ¹ 600
Calculate the P-value for this test. Round your answer to the nearest thousandth. Answer should be between 0 and 1. Note: WebCT answer may be off by a few thousandths but the tolerance is set to handle those discrepancies.

Question 12 (9 marks)
A very large school system wishes to know how it compares to the national average on the SAT Math. The national average is m = 600, the population standard deviation is s = 114. They believe that their students are scoring below the national average. A SRS of 35 students is chosen and their average on the SAT Math is found to be 585. The null and alternative hypothesis are:
H0: m = 600
Ha: m < 600
Calculate the P-value for this test. Round your answer to the nearest thousandth. Answer should be between 0 and 1. Note: WebCT answer may be off by a few thousandths but the tolerance is set to handle those discrepancies.
