Question

confused on how to find the IQR= 7.5

SUURENT A professional hockey player played 20 seasons. The following table shows the number of games in which he played during each of his 20 seasons. Complete parts (a through (e) below. 35 65 77 73 72 77 43 65 75 67 70 72 80 74 82 76 70 75 71 69 D. The data span roughly 7.5 games played c. Find and interpret the five-number summary 35 68 72 75. 5 82 (Type integers or decimals. Use ascending order.) Interpret the five-number summary. Choose the correct answer below. A. The first quarter has the greatest variation. The middle 50% has the next largest variation and the last quarter has the least variation O B. There aren't as many seasons in the fourth quarter as there are in the first quarter . The middle 50% has the greatest variation in the data set. The first and fourth quarters have the least variation OD. The first quarter has the most seasons recorded. The last quarter has the least amount of seasons recorded d. Identify potential outliers, if any. Choose the correct answer below and, if necessary, fill in the answer box to complete your choice O A. The potential outlier(s) is(are) 1. (Type an integer or a decimal. Use a comma to separato answers as needed) OB. There are no potential outiers

Answer 1

As mention in question c ) five number summary is

minimum = 36   

Q1 = Quartile1 = 68

Q2 =Quarile 2 = 72

Q3 =Third Quartile =75.5

Maximum =82

  

we want inter-quartile range (IQR)

formula = third quartile value - First quartile value

IOR = 75.5 -68

IQR = 7.5
