- If a data set has an even number of observations, the medianIn what situations would you see a large difference between the mean and median of a data set? Give specific situations where that may be the case, and explain your reasoning.A sports columnist wishes to portray baseball players as overpaid. Which measure of center should he report as the representative salary of major league players. the mean the median either mean or the median since they will be equal neither the mean nor the median, since both will be much lower than the actual average salary
- In Statsville there’s a city-wide speed limit of 30 mph.If you are caught speeding the fine is $100 plus $10 forevery mile per hour you were over the speed limit. Forexample, if you’re ticketed for going 45 mph, your fine is100 + 10145 - 302 = +250. Last month all the driverswho were fined for speeding averaged 42 mph with astandard deviation of 7 mph. What were the mean andstandard deviation of the fines?A) $120 and $70 B) $220 and $7C) $220 and $70 D) $220 and $170E) $420 and $70There are two national college-entrance examinations, the scholastic aptitude test (SAT) and the American College Testing program (ACT). Scores on the SATs are approximately normal with mean 500 and standard deviation 100. Scores on the ACTs are approximately normal with mean 18 and standard deviation 6. Use the links provided for the Normal (Links to an external site.)calculator and the Inverse Normal (Links to an external site.) calculator to help complete the problems, you do not need to do any work out by hand. (instructions on how to use these calculators can be found in the week 5 star on the home page) a) What percent of all SAT scores are above 600? b) Which is the greater accomplishment, scoring 630 on the SAT or 22 on the ACT ? Explain your reasoning for your choice. c) How high a score in the SAT is needed to place in the top 2.5%.If the median of a data set is 134 and the mean is 177, which of the following is most likely?
- True or false. If the IQR of a data set is 0, then the median is equal to Q3.When an observation that is much larger than the rest of the data is added to a data set the value of the median will increase substantially . True or False?A report states that the mean household income last year for a certain rural county was $55,300 and the median was $62,800. If a histogram were constructed for the incomes of all households in the county, would you expect it to be skewed to the right, skewed to the left, or approximately symmetric?
