Lab 7
What are some faults with this type of data collection? What other types of data collection could you have used, and how might this have affected your study?
Give a point estimate (mean) for the average height of all people at the place where you work. Start by putting the 20 heights you are working with into the blue Data column of the spreadsheet. What is your point estimate, and what does this mean?
Find a 95% confidence interval for the true mean height of all the people at your place of work. What is the interval? [see screenshot below]
Give a practical interpretation of the interval you found in part b, and explain carefully what the output means. (For example, you might say, “I am 95% confident that the true mean height of all of the people in my company is between 64 inches and 68 inches”).
