1. During our semester in statistics, we will be studying inferential statistics. In chapter 1, we learned the basic premises behind inferential statistics. Write a sentence or two summarizing inferential statistics in your own words. 2. The inferential statistics that we will cover in our class will all be parametric statistics. Parametric statistics require that certain requirements about the distribution must be met by the sample data values. We have learned some different distributions in chapter 2. 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. Be certain to include the words "resistant" and "non- resistant" in your explanation. Use the following data sets in problems #4 - #6. Data Set 1: A genetic study 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 that the body 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 4. For each of the data sets, calculate the mean and median. Based on the mean and median, what is the most likely distribution of each data set? 5. Construct 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
