Answer

Explanation:

Step1: Count total number of data - points

Count all the dots in the dot - plot. There are 10 + 5+3 + 3+1=22 data - points.

Step2: Analyze Option A

Number of customers who feed 3 or 4 times a day: There are 3 dots for 3 feedings and 3 dots for 4 feedings. So, the number of customers who feed 3 or 4 times a day is 3 + 3=6. The percentage is $\frac{6}{22}\times100%\approx27.3%\neq30%$.

Step3: Analyze Option B

Number of customers who feed 5 times a day: There is 1 dot for 5 feedings. The percentage is $\frac{1}{22}\times100%\approx4.5%\approx4%$.

Step4: Analyze Option C

Number of customers who feed less than 4 times a day: There are 10 dots for 1 feeding, 5 dots for 2 feedings and 3 dots for 3 feedings. So, the number of customers who feed less than 4 times a day is 10 + 5+3 = 18. The percentage is $\frac{18}{22}\times100%\approx81.8%\approx80%$.

Step5: Analyze Option D

Number of customers who feed less than 3 times a day: There are 10 dots for 1 feeding and 5 dots for 2 feedings. So, the number of customers who feed less than 3 times a day is 10 + 5=15. The percentage is $\frac{15}{22}\times100%\approx68.2%\approx65%$.

Answer:

A. 30% of the customers surveyed feed their cat 3 or 4 times a day.
