Question

newspaper reporter wants to know how popular the hobby of bird watching is in the city. He asked people at the local bird refuge if they watched birds as a hobby. Which of the following best explains whether the reporter's data is valid or not?
A. The data is valid for the entire city because the bird refuge is located in the city.
B. The data is not valid for the entire city because people can have more than one hobby.
C. The data is not valid for the entire city because bird watchers are more likely to visit a bird refuge.
D. The data is valid for the entire city because a bird refuge is a good place to find people who like to watch birds.
I think its c or d

Answer 1

I'm not the best at math so any help would work

Answer 2

I think c is the best choice. I would have said the data were not valid because the city was not randomly sampled. Securing data from the bird refuge is not sampling the city.

Answer 3

ok i will go with that

Answer 4

honestly, this seems more as a science question more than a math question but I think its C. You want to know how many people in the city watch birds. The reporter's data is not valid because he's only surveyed bird watchers. He's ignored the 90% or so of the people who don't go to the bird refuge.

Answer 5

Technically this is a statistics question. Generally statistics is taught in math; however, scientists get a taste of that too because their work is based on results that are statistically valid.

Answer 6

imagine not cheating and actually being smart totally not you 100%. totally not me 100%
