Step-by-step explanation:
Solving (a):
First, we categorize each data (to get their frequencies):
PI PI PI PI PI PI PI PI PI ---> Frequency: 9
S S S S S S S S---> Frequency: 8
V V V V V V V V V V V V V ---> Frequency: 13
PO PO PO---> Frequency: 3
B ---> Frequency: 1
C C ---> Frequency: 2
Total = 36.
The frequency table is as follows:
Solving (b): The relative frequency and percentage.
Relative frequency is calculated by dividing each frequency by the total frequency.
So, we have:
The percentage is calculated by multiplying the frequency by 100%.
So, we have:
Solving (c): Percentage that mentioned vegetables and fruits, poultry, or cheese?.
This is calculated as:
(d) See attachment for bar graph
What you have to do is divide. Divide 720 - 60 = 12. So there are 12
-13v=195
divided each side by -13: v = -15
