7th grade 70 40 110
8th grade 90 110 200
totals 160 150 310
Gloria surveyed all of the campers to determine their preferred field trip. The results are displayed in the table. Which of the following is a relative frequency that can be found with the table? Round the percentage to the nearest tenth.

Answer 1

wrong the answer are 40% 90% 70% and 32%

Answer 2

so what is the percentage

Answer 3

To find the relative frequency of a certain category (e.g. beach field trip for 7th graders), we need to divide the frequency of that category by the total number of responses.

For the 7th graders and beach field trip:
Relative frequency = 70 / 310 = 0.2258

Rounded to the nearest tenth, the relative frequency of 7th graders choosing the beach field trip is 22.6%.

Answer 4

Apologies for the error in my previous response. Here are the correct relative frequencies for each category based on the table provided:

- 7th grade and Seacoast field trip: 70 / 310 = 0.2258 -> 22.6%
- 7th grade and Mountains field trip: 40 / 310 = 0.129 -> 12.9%
- 8th grade and Seacoast field trip: 90 / 310 = 0.2903 -> 29%
- 8th grade and Mountains field trip: 110 / 310 = 0.3548 -> 35.5%

Again, I apologize for the initial mistake in my calculation. Thank you for pointing that out.

Answer 5

The correct relative frequencies, rounded to the nearest whole percentage, are as follows:

- 7th grade and Seacoast field trip: 22.6%
- 7th grade and Mountains field trip: 12.9%
- 8th grade and Seacoast field trip: 29%
- 8th grade and Mountains field trip: 35.5%
