So we have five data points. So let's divide 29.65 divided by five, and we get 5.93 feet. So here our sample mean, and I'm going to denote it with an X with a bar over it, is, and I already forgot the number, 5.93 feet. 5.93 feet. This is our sample mean, or if we wanna make it clear, sample arithmetic mean. And when we're taking this calculation based on a sample, and then somehow we're trying to estimate it for the entire population, we call this right over here, we call it a statistic. We call it a statistic.
