You will be comparing two sets of data for this assignment. 1. Determine the average number of toilet paper rolls* for Fall 2022 biochemistry and genetics students (individually) and calculate the standard deviation of each using the equation. Please be sure to show your work. I know that you can easily use tools like Microsoft Excel to calculate standard deviation, but I would like to see you complete the work by hand so that you get a sense of the role of each component of the equation. Ignore students that did not provide answers (don't use those students in the mean or N value calculations). 2. Please answer the following questions when you submit your data. Which group had a higher mean number of rolls of toilet paper? Which value had the most variability? Referring to the equation, how could you decrease the amount of variability in the mean? Did you find the variation surprising or unexpected? The two sets of data and the standard deviation formula pictures are attached…

The chart to the right shows that a professor's grading distribution is bell shaped, or normally shaped. The mean of the distribution is 74 and the standard deviation is 9. Using a Continuous Variable Normal Bell Distribution Model, calculate the minimum test score needed to score in the top 5% of the class. Complete your work in the worksheet by listing the formula inputs, labels for the formula inputs and make your calculations with formulas. This test problem is similar to what you studied in video # 32, 33 and 34 and homework problems # 17, 21 and 23.

Because the mean is very sensitive to extreme values, it is not a resistant measure of center. By deleting some low values and high values, the trimmed mean is more resistant. To find the 10% trimmed mean for a data set, first arrange the data in order, then delete the bottom 10% of the values and delete the top 10% of the values, then calculate the mean of the remaining values. Use axial loads (pounds) of aluminum cans listed below for cans that are 0.0111 in. thick. Identify any outliers, then compare the median, mean, 10% trimmed mean, and 20% trimmed mean. 247 261 269 273 275 280 282 282 284 285 285 287 290 292 293 296 296 299 311 507 Identify any outliers. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The outlier(s) is/are pounds. (Type a whole number. Use a comma to separate answers as needed.) C OB. There are no outliers.
