Q:

PLEASE HELP!!!!! only correct answer stop answering if it is the wrong answer4

Exercise 8-15

Consider the following data that shows a portion of poin of sales transactions from a local bookstore. Each binary variable indicates whether or not a particular book genre is purchased within a transaction.

Sci-fi fiction	Travel guide	Self help	Biography	Children book
0	0	1	1	1
1	0	1	0	1
0	1	1	0	0
0	0	1	0	0
0	1	0	1	1
1	0	0	0	0

a. Using the first five sales transactions, compute the matching coefficients for all pairwise observations for the five binary variables. (Round your answers to 2 decimal places.)

b. Using the first five sales transactions, compute Jaccards coefficients for all pairwise observations for the five binary variables. (Round your answers to 2 decimal places.)

c-1. Based on Jaccard's coefficients, which of the following transactions is the most similar pair?

multiple choice 1

• Observations 3 and 4

• Observations 4 and 1

• Observations 3 and 1 Incorrect

• Observations 2 and 5

c-2. Based on Jaccard's coefficients, which of the following transactions is the least similar pair?

multiple choice 2

• Observations 4 and 5

• Observations 4 and 3 Incorrect

• Observations 5 and 2

• Observations 2 and 3
