A researcher wants to find the average height of the residents in a city. There are too many people to take everyone’s height, so he divides the town into different neighborhoods and takes the height of five people who live in each neighborhood. He then takes the mean of the five heights in each neighborhood to create a sampling distribution. He calculates the mean of the sampling distribution to be 67 inches with a standard deviation of 9 inches. What can he conclude?

The average height of people in the city is 67 inches, and most people are within 9 inches of that.
The samples do not represent the population well because the standard deviation of the sampling distribution is high.
The average height of each sample is 67 inches.
Each sample ranges from 58 to 76 inches
