AP Statistics

Your mathematics instructor claims that, over the years, 88% of his students have said that math is their favorite subject. In this year's class, however, only 21 out of 32 students named math as their favorite class. The instructor decides to construct a confidence interval for the true population proportion based on the sample value. What's the correct value for the standard error of SE in this case?

  1. Formula:

    Standard error = √(pq/n)

    With your data:
    p = 21/32 (convert to a decimal); q = 1 - p; and n = 32 (sample size).

    Plug the values into the formula and calculate.
