7. Make a box and whisker plot of the following data. Show your work as to how you calculated the different key points on the box-and-whisker plot.
21, 25, 30, 27, 22, 23, 23, 24, 26, 28, 25, 22, 23
8. Compare the following two sets of data by using box-and-whisker plots. Explain the similarities and differences between the two data sets.
Set A = {56, 62, 71, 82, 92, 101, 106, 103, 97, 84, 68, 57}
Set B = {36, 42, 48, 56, 63, 72, 78, 75, 69, 58, 46, 37}
9. Make a dot plot for each set of data. Compare and contrast the shape, spread, and center of the data.
Set A = {4, 5, 6, 3, 3, 2, 4, 5, 8, 2, 5, 13}
Set B = {5, 6, 4, 2, 8, 4, 5, 6, 5, 2, 8, 3, 7, 3}
10. Determine the shape and explain what type of distribution the data has.
110, 107, 105, 108, 108, 107, 108, 105, 106, 87, 85, 88, 89, 92, 95, 96, 94, 95, 91, 90, 100, 99, 98, 97, 95, 92, 105
12. A recent social survey asked respondents whether they like Apple or Microsoft. The responses were recorded in the following table.
Male Female Total
Apple 152 194 346
Microsoft 168 126 294
Total 320 320 640
a. A respondent is randomly selected among those that prefer Apple, what is the probability that the respondent will be female?
b. A respondent is randomly selected among those that are Male, what is the probability that the respondent prefers Apple?
c. What is the relative frequency of a female who prefers Microsoft?
