A statistics instructor would like to know whether it is worthwhile to require students to do weekly homework assignments. For Section1 of the course, homework is assigned, collected and graded each week. In Section2, students are not required to turn in homework. At the end of the semester, the students are given the same final exam. In Section1, the numbers of students getting each grade are: 16 students got A, 22 students got B, 8 students got C, and 4 students got D. In Section2, the numbers of students getting each grade are: 8 students got A, 18 students got B, 18 students got C, and 6 students got D. Is there an association between assigning homework and exam grade? Test at the alpha = 0.05 level. a. We reject the null hypothesis with two-tailed critical values; there is an association between assigning homework and exam grade. b. We reject the null hypothesis with one-tailed critical value; there is an association between assigning homework and exam…
In a traditional class with in-class tests, a question that is often asked after a class exam is, "What was the class average?" If that question is asked and the professor says that the class average was 80, what information do the students gain by knowing that? I want you to focus on both what the individual students knows about their own grade as well as what the students know about the class's grades on that exam.

A company has 30 employees, including a director. The lowest salary among the 30 employees is $22,000. The director’s salary is $180,000, which is more than twice as much as anyone else’s salary. Decide for each of the following statements about the 30 salaries whether it is true, false, or you cannot tell on the basis of the information at hand. • The median salary is below $60,000.• The average salary is below $60,000.• If all salaries are increased by $1,000, that adds $1,000 to the average.• If the director’s salary is doubled, and all other salaries remain the same, that increases the average salary.• If the director’s salary is doubled, and all other salaries remain the same, that increases the median salary.• The standard deviation of the salaries is larger than $180,000

One morning Dave an email message to Alvin that said the following: “You are one of my dearest friends. If you care about me, send a copy of this letter to two of your dearest friends tomorrow. If you do not break this chain, you will live long and prosper.” Alvin followed the directions: the next day he sent a copy of the message to two of his dearest friends. The following day, each of the recipients did the same. Count the day Dave sent the original message as the first day, and assume the chain is unbroken. A. How many copies of the message will be sent on the sixth day? B. Find the n-rule that will show how many copies of the message will sent on the n-th day.

Assume that the U.S Open Golf Tournament was played at Congressional Country club, with prizes ranging from $465,000 for first place to $5000. Par for the course is 70. The tournament consists of four rounds played on different days. Suppose the scores for each round of the 32 players who placed in the money (more than $17,000) were given on a web site. The scores for the first round were as follows: 71 66 68 72 74 73 71 71 74 73 73 71 75 71 72 71 78 75 71 71 74 75 66 75 75 76 71 72 72 73 71 67
