Hi, I need some help with questions 5 and 6. I attached a photo of the data set and questions 5 and 6. We are allowed to use excel to find the answers for this project, but I am struggling with doing it by hand too if you could show me the steps. Thank you so much.

I chose to focus on the height question. Heights of Students in Statistics Class (in inches): 57, 59, 60, 62, 63, 64, 65, 65, 66, 67, 68, 68, 68, 68, 69, 69, 70, 71, 71, 72, 72, 72, 74, 75 2. Think about the question. For example, hair color, how many people in this class do you think have red hair. Going into this, I wanted to get a good estimate of what the average may be by looking at data on the heights of people in the United States. However, typically height is measured in terms of female height and male height. This complicated the situation and made it a bit more difficult to analyze the data in this way. I was afraid if I analyzed the data separately as male height and female height though, the sample would be far too small. I am going into this looking at height of all people regardless of gender.
