Statistics - 10.4.1 Hypothesis Testing for Population Proportions - 1-Tailed

This is the last one-sample test we will look at. Note that your textbook does cover intervals for variance and standard deviation, but we won't cover those in our course. These tests are for population proportions, which uses the normal model and the values given are a percentage or part of a whole.
