Answer:
I'll try my best but I'm pretty sure if 20 people out of 50 surveyed stated that they preferred spring over the summer season, you can calculate the percentage of people who preferred spring as follows:
Percentage = (Number of people who preferred spring / Total number surveyed) x 100
Percentage = (20 / 50) x 100 = 40%
So, 40% of the people surveyed preferred spring over the summer season. The statement that 20% preferred spring appears to be incorrect; the correct percentage is 40%.
