people in the world. There are no right or wrong answers, so just answer honestly!

III. Think about someone you know who has worked hard towards a long-term goal. Remember (and this is
important), this exercise is not about someone overcoming hardships in life and then doing well. This
assignment is to ask all you can about someone who set a difficult, far-off goal, and was able to achieve it.
What was the goal your gritty person was aiming for, what were the obstacles/struggles your person had to
overcome and how were they able to manage those, and what is their life like now that they accomplished the
big goal. Summarize that information here. (Write at least five sentences here)
The following infographic is a real world example of two approximately normal distributions, made up
of a survey on the height distributions of 4,600 husbands and wives in the United States in 2009.
8a. Which distribution belongs to
the husbands and which to the
wives? Why do you believe that?
Height distribution of husbands and wives
Percentage of people
8b. What do you believe is the
mean height for the wives?
8c. Which distribution has a
smaller standard deviation?
8d. What height would you estimate to separate the shortest 30% of husbands from the taller 70%?
8e. What two heights would you estimate to contain the middle 50% of wives?
7a. What marathon time has the highest
frequency? Why do you think that is?
The following infographic is a real world example of an approximately normal distribution, made up of
around 9 million marathon (26.2 miles) finishing times (in hours and minutes).
Distribution of Marathon Finishing Times
7b. What would you estimate the mean
marathon time to be, and why?
Number of Finlshers (in thousands)
3:30 4:00 4:30 5:00 5:30 6:00
Finish Time (one-minute increments)
7c. What marathon time would you estimate to separate the fastest 5% of finishers from the other 95%?
7d. What marathon time would you estimate to separate the slowest 20% of finishers from the other
big would you
Why do you think that is?
4. For the last two exercises, what do you notice about the estimated numerical values of your z-scores?
5. Is this the correct picture for a z -score that separates the bottom 85% of the data from the top 15%.
Why or why not?
6a. Given the diagram below, circle which area to the right you think is shaded out of the options below:
• 5% to the right of z
• 10% to the right of z
• 90% to the right of z
• 1% to the right of z
6b. Why did you choose this answer out of the four options? What does that mean the area to the left
6c. Do you think the z-score we find will be negative, zero, or positive? Explain your reasoning.
