Answer:
IQR for males: 3
IQR for females: 2
Q1 for males: 5
Q1 for females: 6
the number of females who spend over 6 hours exercising is greater(?) than the number of males who spent 6 hours exercising
Step-by-step explanation:
An equal amount of men and women were randomly selected and asked how many hours per week they spend excercising
How to find IQR?
to find IQR you have to identify your median(middle value) of the lower and upper half of the data. These are called quartile 1(Q1) and quartile 3(Q3). You subtract these two (Q3 and Q1) and the IQR is the difference.
Males box plot:
Minimum: 1
Maximum: 10
Q1: 5
Q2: 7
Q3: 8
Subtract Q3 and Q1
8 - 5 = 3
This is the IQR
Females box plot:
Minimum: 4
Maximum: 10
Q1: 6
Q2: 7
Q3: 8
Subtract Q3 and Q1
8 - 6 = 2
IQR =2
the number of females who spend over 6 hours exercising is greater than the number of males who spent 6 hours exercising
