I am setting a new standard assessment and want the pass rate in the population to be 90%. As a trial, I select 80 participants and ask them to complete the standard assessment. I achieve 73 passes and 7 fails. Null Hypothesis: Population Pass Rate equals 0.9 Alternative Hypothesis: Population Pass Rate not equal to 0.9 Are the assumptions satisfied for me to proceed with the test? Yes, the sample size of 80 exceeds 30 so the central limit theorem will hold O No, I do not have at least 10 passes and 10 fails Yes, but I must use t instead of Z as the sample size is not very large
