Final answer:
It is not possible to predict how many more students would choose dogs as a favorite type of pet than cats based on the given information.
Step-by-step explanation:
To predict how many more students would choose dogs as a favorite type of pet than cats, we need to analyze the survey results provided. From the given table, we can see that 30 students were surveyed, and the favorite pet choices were recorded. However, we do not have the actual number of students who chose dogs or cats as their favorite pets. Therefore, it is not possible to predict how many more students would choose dogs over cats based on the information provided.
The student asked about predicting the number of students who would choose dogs over cats as their favorite pet, based on a survey conducted with 30 students. To solve this, we need to find the proportion of students who prefer dogs over cats from the survey and then apply that proportion to the total school population.
Assuming the survey shows that a certain number of students prefer dogs and a different number prefer cats, let's say X prefer dogs and Y prefer cats. The ratio of preference for dogs over cats is then (X-Y)/30. Multiply this ratio by the total school population (210) to estimate the difference at the school level. The calculation would be ((X-Y)/30) × 210 to get the predicted difference in preference for the entire school.
Without the actual numbers from the survey result, we can't provide a specific answer. Once the numbers are known, replace X and Y with those numbers and follow the step-by-step calculation provided.
