A survey was conducted of 130 purchasers of new BMW 3 series cars, 130 purchasers of new BMW 5 series cars, and 130 purchasers of new BMW 7 series cars. In it, people were asked the age they were when they purchased their car. The following box plots display the results. 25 - Part (a) 8Mw35eries l::l' BMWSsevies g BMw75eIies E G-tilttllittlH 35 40 45 50 55 60 65 30 70 75 80 In complete sentences, describe what the shape of each box plot implies about the distribution of the data collected for that car series. Each box plot is spread out more in the values. Each plot is skewed to the --Select--- v , so the ages of the top 50% of buyers are -Select- v variable than the ages of the lower 50%. - Part (b) Which group is most likely to have an outlier? Explain how you determined that. The ---Select-- V - Part (0) is most likely to have an outlier. It has the ---Select- Compare the three box plots. What do they imply about the age of purchasing a BMW from the series when compared to each other? Comparing the median ages, younger people tend to by the --Se|ect--- v in each data set. ---Select--- V , while older people tend to buy the ---Select--- V . This is not a rule, because there is so much Part (d) Look at the BMW 5 series. Which quarter has the smallest spread of data? first quarter second quarter O third quarter fourth quarter What is the spread? Part (e) Look at the BMW 5 series. Which quarter has the largest spread of data? first quarter second quarter O third quarter O fourth quarter What is the spread? Part (f) Look at the BMW 5 series. Estimate the interquartile range (IQR). IQR =3 Part (9) Look at the BMW 5 series. Are there more data in the interval 31 to 38 or in the interval 45 to 55'? How do you know this? 0 There are more data in the interval 31 to 38 because it is the lowest interval and the data are right-skewed. 0 There are more data in the interval 45 to 55 because it has the wider range. 0 There is not enough information to tell, because both intervals lie within quarters and it is not possible to judge the spread of data within quarters. E] Part (h) Look at the BMW 5 series. Which interval has the fewest data in it? How do you know this? 1. 31-35 2. 38-41 3. 41-64 The interval ---Select--- V has the fewest data in it. It has --Select-- v 25% of the data, while the other two intervals each have 25% of the data
