1. Identify the level of measurement used in this study.
2. Create a Frequency Table with 6 classes.
3. Create a Histogram based on the Frequency table in problem 2.
4. Find the mean, median, and mode of the number of chocolate bars consumed by 16-year-old girls in a month.
5. Find the Variance and Standard Deviation of the number of chocolate bars consumed by 16-year-old girls in a month.

I will give you a partial solution:
---
much of the information you seek can be had as follows:
copy and paste the list of given samples into the input box here:

---
mean = 37.7
sample variance = 398.21724137931
sample standard deviation = 19.955381263692
mode = 52
---
as for the table and histogram, you can do that yourself
