Week 11, Lab 12

Hypothesis testing continuation

Means and Proportions

This lab has 3 videos. In the first one, below, we review how to establish a null hypothesis, we also talk about the differences between one or two-tailed tests; and we go through the steps to carry out one-sample hypothesis testing.

The other two videos are concrete examples of how you carry out one-sample hypothesis testing for means and for proportions.

One-sample hypothesis testing for means

In the video below, we see an example of how to solve a hypothesis testing for means. Remember the formula that we use for one sample means:

One-sample hypothesis testing for proportions

In the video below, we see an example of how to solve hypothesis testing for proportions. Proportions just refer to percentages. The formula for carrying out one sample hypothesis for proportions is this:
