Use the following data sets in problems Data Set 1: A genetic study fish was performed on the number of armored plates found on stickleback fish
A random sample of 40 stickleback fish showed the following number of plates
42 64 62 9 12 62 50 12 27 11
65 64 63 21 49 62 43 65 51 62
12 21 62 62 66 9 64 12 63 10
54 21 61 9 20 63 45 57 60 62
Data Set 2: It has been hypothesized distributed that the temperature of healthy adult humans is normally distributed. A random sample of 25 healthy adults resulted in the following body temperatures:
98.5 98.6 97.8 98.9 97.9 99 98.2 98.7 98.8 99
98 99.2 99.5 99.4 98.3 99.1 98.4 97.6 97.4 97.7
97.5 98.8 98.6 99.3 98.4
1. During our semester in statistics, we will be studying interential statintics. in chapter 1, we leamed the basic premises behind inferential inferential statistics in your own words. Wiite a sentence or two summarizing inferential statistics in your own words.
2. The inferential statistics that we will cover in our class will al be paremetrie statistics. Parametric statistics require that certain requirements about the distribution must be met by the sample data values. Sketch and name the FOUR different distributions that we have learned.
3. We have also learned that the mean and the median can give us hints about the distribution of our data. Explain how the different distributions typically affect the mean and the median.
4. For each of the data sets, calculate the mean and median. Based on the mean and is the most likely distribution of each data set?
5. Construct a stem-and-leaf plot and a boxplot for EACH data set.
6. Do the graphs in #5 support your answers to #4? Justify your answer using a complete sentence(s) and proper grammar.
