A retail store started a new inventory system on January 1, 2019. The loss prevention manager compared the number of units that were missing from each month's inventory in 2018 with the number of units that were missing from each month's inventory in 2019. The results are provided in the table below. 2018 2019 87 7171 79 75 91 67 78 76 82 68 75 65 88 72 86 75 83 64 77 70 89 73 83 63 What conclusion could be made using the median and interquartile range from the data? The median for 2018 is 83, which is greater than 70.5, the median for 2019. The interquartile range for 2018 is 9, which is greater than the interquartile range for 2019, 8. The median for 2018 is 6969, which is less than 82.5, the median for 2019. The interquartile range for 2018 is 8.5, which is the same as the interquartile range for 2019. The median for 2018 is 83, which is greater than 71, the median for 2019. The interquartile range for 2018 is 16, which is greater…

1. A professor is interested in how attendance is related to grades her class. She goes through her records and determines each student’s final average and the number of days absent. The scores for her sample are given in the table below. a. Construct a scatter plot of the relationship between final averages and the number of days absent. b. Is there a significant relationship between final averages and the number of days absent? Calculate and interpret the correlation and report it in proper APA format. c. Compute r2 for the data. What percent of the variability in final averages is accounted for by the number days absent?

Suppose the mean price for used cars is $10,198. A manager of a Kansas City used car dealership reviewed a sample of 50 recent used car sales at the dealership in an attempt to determine whether the population mean price for used cars at this particular dealership differed from the national mean. The prices for the sample of 50 cars are shown in the file named UsedCars. 12,400 10,400 12,100 10,000 11,000 8,895 7,675 9,975 6,350 10,470 9,895 11,250 8,795 12,500 9,340 10,150 9,200 9,395 11,000 10,640 10,000 7,500 8,000 10,440 10,200 10,300 9,740 9,280 10,930 8,000 9,000 7,680 9,400 10,730 7,350 12,240 11,970 8,240 9,910 10,080 9,440 8,970 9,500 10,050 10,130 11,400 8,500 7,500 9,090 10,500 (a) Formulate the hypotheses that can be used to determine whether a difference exists in the mean price for used cars at the dealership.
