Step 2: Read the information below and answer the questions. Write your own Module 3 homework problem! 1. What variable and population will you be measuring? (ex, heights of all 1" graders, etc) 2. Justify why you think it would follow a normal distribution and not have a different shape (skewed, ste). 3. What is an appropriate mean for this population? (you can use google to help!) 4. What is an appropriate standard deviation for this population? (sometimes it's hard to find a standard deviation, so do your best to pick something reasonable. One hint is to think about the 68/95/99.7 "empirical rule") 5. Label the axes of the distribution below based on your answers Write a module 3 style question about your distribution below. Write the solution to the question you just wrote. Scanned with CamScanner8. Write another module 3 style question about your distribution below. 9. Write the solution to the question you just wrote. Step 3: Your classmates, Maya and Salik, are talking. Here is their conversation. Respond in the places that say "your response." Salik: I think shoe sizes could be something normally distributed! Maya: Ok, that's a good variable to use. What population are we considering? I think we need to narrow it down, so probably just adults. If we look at all adults will it look like a normal distribution, or do we need to account for differences in men/women? Your response (what do you think? Justify your answer): Salik: Let's do only women's shoe sizes just in case. Maya: Ok, so I think the average should be somewhere around 7 or 8? Then based on what I see at stores I think the smallest is probably 4 and largest is 12? Salik: Let's do 8 as the mean since that is right in the middle of 4 and 12. What could we make the standard deviation so that it goes from 4 to 12 with & in the middle? Maya: If the standard deviation is I then it will go from 5 to I I, and if the standard deviation is 2 then it will go from 2 to 14. So let's try 1.5? Can you label it? - Your response: Salik: OK then we can pick a shoe size and ask a z-score question. Maya: My shoe size is 6. so what is the z score for my feet?

Your response (write out the solution with work): Salik; Then we can use the 68/95/99.7 rule and ask what shoe sizes have the middle 68% between them.
