Ann [662]

Solution:

We are given below frequency table:

Amusement-Park Museum Broadway-Show Total

Juniors 57 21 42 120

Seniors 64 44 58 166

Total 121 65 100 286

We have to find the percentage of surveyed students who chose the amusement park.

From the table, we see there are total 121 students who chose amusement park out of total 286 students.

Therefore, the percentage of surveyed students who chose the amusement park is given below:

$\frac{121}{286}\times 100=42.3\%$

Hence, the option A. 42.30% correct.
