To estimate how many students in the entire school prefer animated movies based on Tan's sample data, we can use proportions.
-
Calculate the proportion of students in the sample who prefer animated movies: \[ \text{Proportion of animated movie fans} = \frac{\text{Number of students who prefer animated}}{\text{Total number of surveyed students}} = \frac{48}{120} \]
Calculating this gives: \[ \frac{48}{120} = 0.4 \]
-
Now, apply this proportion to the total number of students in the school: \[ \text{Estimated number of students who prefer animated movies} = \text{Total students} \times \text{Proportion} = 628 \times 0.4 \]
Calculating this: \[ 628 \times 0.4 = 251.2 \]
Since we generally round to the nearest whole number, we estimate that approximately 251 students in the school prefer animated movies.
Therefore, the correct response is: 251
