We are pulmonologists (doctors who treat lungs), examining lung function in adults with cystic fibrosis. We find the following values for FEV1, a measure of airway obstruction (already sorted). 34 35 45 47 Q1 = (45+47)/2 = 46 48 51 59 60 66 70 Q3 (66+70)/2= 68 = 86 113 Fill in the following missing quantities using the data above. If an answer does not exist, write NA Lowest outlier = Lower fence = Lower whisker = Q1 = 46 Median = 55 Q3 = 68 Upper whisker = Upper fence = Highest outlier = median = 55 Un

In a study of exhaust emissions from school buses, the pollution intake by passengers was determined for a sample of nine school buses used in the Southern California Air Basin. The pollution intake is the amount of exhaust emissions, in grams per person, that would be inhaled while traveling on the bus during its usual 18-mile trip on congested freeways from South Central LA to a magnet school in West LA. Here are the amounts for the nine buses when driven with the windows open. 1.17     0.33    0.40     0.33     1.32     0.38     0.25     0.40     0.35   (a) Consider making a stemplot. Are there outliers or strong skewness that would preclude use of the t procedures? Which is correct? A. The sample is small and the stemplot is right skewed with possible outliers, so use of t procedures is not appropriate. b. The distribution is symmetric so use of t procedures is appropriate.    c. The sample is small and the stemplot is left skewed with possible outliers, so use of t procedures is…

Beanie babies are toy stuffed animals that have become valuable collector’s items. Beanie World Magazine provided the age, retired status (R for Retired and C for Current), and value of 50 Beanie babies. The data Beanie can be downloaded from Blackboard.
