Professional athletes are threatening to strike because they claim that they are underpaid. The team owners have released a statement that says, “The average salary for players was $1.2 million last year.” The players counter with their own statement that says, in part, “The average players earned only $750,000 last year.” Is either side necessarily lying? Hearing this on the news, what questions would you ask about these statistics?
1)Should you use the median or mean to describe a data set if the data are not skewed? 2) You may read in the newspaper that a study of a new drug for cancer “increased survival by an average of 8weeks.” It turns out that this is a median, and it is used for complicated statistical reasons. But in a perfectworld, would you prefer to know the increase in mean or median survival? 3) If the median house price is $1.9m, does that necessarily mean that half of the houses on the block areworth less than $1.9m and half worth more?

Hi, I want to know two answers for my statistics class, the first question is how to find the relative risk for receiving a parking ticket for students who commuted by car and those who did not? The second question is to find the risk of having ever received a parking ticket for students who commuted by car? If you could please help, I am struggling a lot with these homework questions! The contingency table is below. In a survey for a statistics class project, students in the class were asked whether they commute to school by car (Yes or No) and whether they had ever received a parking ticket (Yes or No). Of the 23 students who commuted to school by car, 19 had received a parking ticket. Of the 25 students who did not commute to school by car, 7 had received a parking ticket. Here is a contingency table for these data. Received parking ticket? Yes No Total Commute 19 4 23 Doesn’t commute 7 18 25 Total 26 22 48

2. A medical researcher is testing the effectiveness of a new drug for treating Parkinson's disease. Ten subjects with the disease are given the new drug and 10 are given a placebo. Improvement in symptomology is measured. What would be the roles of descriptive and inferential statistics in the analysis of these data?
You saw back in Chapter 2 that the mean, median, mode, and midrange are used to indicate where data is centered in a data set, or in other words what a typical value in the set is. A question that is often asked is, "If they're all supposed to do the same thing, why is there more than one?" Isn't one enough? In this exercise, you will be given two small sets of data. For each set, a. find the mean, median, mode and midrange b. in your opinion, decide which of the measures BEST represents all the values in the set (best indicates a typical value), and which one does this the WORST. c. post your responses and justify them by explaining why Don't forget to respond to at least one of your classmate's posts. With this exercise, "more is better." I'll elaborate after the deadline. • Set A: the salaries of 10 employees at a company (in thousands of dollars): 50, 50, 50, 50, 50, 50, 50, 50, 50, 500 • Set B: the grades of 9 students on an exam: 20, 25, 30, 35, 40, 45, 100, 100, 100
