A study was done to explore the number of chocolate bars consumed by 16-year-old girls in a month's time. The results are shown below. Number of Chocolate Bars Consumed 56 46 12 62 39 24 59 51 39 52 28 41 10 64 27 0 34 5 55 32 42 24 14 63 1 63 52 58 52 26 Use the data from the chocolate bar study to answer the following questions. Use SPSS for all calculations. Copy and paste the SPSS output into the word document, highlighting the correct answer. Additionally, type the correct answer into your word document next to the corresponding question. 1. Identify the level of measurement used in this study. 2. Using SPSS, run descriptive statistics on the data: a. Find the mean, median, and mode of the number of chocolate bars consumed by 16-year-old girls in a month. b. Find the variance and standard deviation of the number of chocolate bars consumed by 16-year-old girls in a month. 3. Create a frequency distribution table with six intervals/classes. 4. Create a histogram based on the Frequency table in problem 3.

Researchers aim to study the weights of 10-year-old girls living in the United States (possibly to compare to other countries and thus compare growth rates). Based on previous studies, we can assume that weights of 10-year-old girls are Normal. From a small sample of 16 girls, the researchers find a sample average of ?̅ = 91.4 pounds and a sample standard deviation of ? = 2.8 pounds. Create a 99% confidence interval for the true average weight of 10-year-old girls...
