The following data are a sample of sepal lengths of 16 specimens of a particular flower. Sepals protect flowers as they develop and support the petals when a flower blooms.

8.4, 9.9, 6.1, 6.8, 1.2, 4, 7.9, 6.8, 5.8, 7.1, 8.1, 7.9, 7.9, 5.8, 7.9, 4.8

Answer the following questions about this data set.

(a) What is the 5-number summary of the data set?

Min	Q1	Median	Q3	Max

(b) What are the mean and standard deviation of the data set? Round to two decimal places.Mean = Standard deviation =

(c) On your paper in the space provided, write the following number: 68457. This lets me know which data set you have. (d) Create a histogram and boxplot of the data set, either by hand or using software. Draw both graphs in the space provided on your paper. Make sure that your graphs are drawn neatly and to scale, and that they are appropriately labeled. (e) In the space provided on your paper, summarize the data set. Make sure to indicate what the numbers in the data set represent (that is, what the sample and variable are) and to completely describe the data set (use CUSS). (f) Use your work above including the graphs to answer the following questions.

a. 75% of all sepal lengths are above b. The middle 50% of all sepal lengths are between ? and ? c. Approximately 90% of all sepal lengths are below
