1) You want to calculate the total weighted entropy of students' heights in your business analytics class. Assume nine students are in the class and divide them into two groups. The first group is those students with a height of 6 feet or less, and the second group is those with a height of more than 6 feet. In the first group, we have 1 Male and 3 Females, and in the second group, we have 2 Females and 3 Males.

Please use this table which shows the calculated value forq

q	1	1/2	1/3	2/3	1/4	3/4	1/5	2/5	3/5	4/5	1/6	5/6
	0.00	0.50	0.53	0.39	0.50	0.31	0.46	0.53	0.44	0.26	0.43	0.22

What'd be the second group's entropy?

2) What is the class's total weighted entropy?
