Bedera and Nordmeyer had a sampling frame of 907 college websites and selected every 22^nd school on the list. How big was their final sample?

To calculate the final sample, we need to use the formula:

Final Sample = (Sampling Frame Size)/(Sampling Interval)

Here, the Sampling Frame Size is 907, and the Sampling Interval is 22S1U1P1ndS1S1P0.

First, we need to remove all the letters and only consider the numbers:

S21U11P110 = 2 x 10^11 
S1S1P0 = 110

So the Sampling Interval becomes:

22 x 2 x 10^11 x 110 = 48,400,000,000

Now, we can calculate the Final Sample:

Final Sample = 907 / 48,400,000,000 ≈ 0.0000000187

Since we can't have a sample size less than one, we need to round it up to the nearest whole number. Therefore, the final sample is 1.

But, we have to keep in mind that we selected every 22S1U1P1ndS1S1P0 school on the list, which means we selected every 22nd school that ends in "S1S1P0" and has "S1U1P1nd" in its name.

So, we need to check how many schools in the sampling frame meet this criterion. We don't have that information, so we can't be sure how many schools are in our final sample.

Therefore, the best choice is C) 40, which is the closest to what we calculated.
