Question

The Hamden board of education wants to know how the community feels about building a new media center for the middle school. They called every tenth person on the registration list of 7,300 voters until they had called a total of 40 voters. Which of the following are true of the sample of 40 voters? Check all that apply.
The sample is not randomly chosen.
The sample should be larger to give more reliable information.
The sample size is too large to make inferences.
The sample size is too small to represent the population.
The sample size is too small and will show larger variation.
The sample is invalid because it randomly chooses voters.
The sample size is too small and can lead to false inferences.

Answer 1

can someone help plz

Answer 2

i think false true false true false false true

Answer 3

I think the main problem with the sample size is that it is too small. The question mentions that they have 7300 members and choose 1 out of 10 but they limited themselves to 40, which is much smaller than the sample they could have gotten.
I agree with your answers, but I think the option "The sample size is too small and will show larger variation." could be true, along with the others

Answer 4

No problem. I hope we're right!

Answer 5

I would go with false true false true true false true
since smaller sample sizes do lead to larger variability than large sample sizes.
