The following are the exam scores for a new literature class: 34, 41, 90, 80, 18, 20, 25, 70, 25, 20, 50, 40, 36. The class follows a typical grading scare where 65% is the lowest passing gradeand 100% is the highest. Create a box plot. Be sure to identify all thenecessary terms. What can we infer from looking at the box plot?
Calculate the 5-number summary of this numerical distribution, and also the IQR and outlier boundaries. Draw a box plot to show all that information. 18, 14, 27, 35, 7, 16, 21, 20, 28, 19

Use the IQR to determine if any of the data in the data set are outliers. {23,80,43,23,0,20,23,23,20,28}{23,80,43,23,0,20,23,23,20,28} Any data value less than Answer or greater than Answer are outliers.
Construct a stem-and-leaf plot of the test scores 67, 72, 86, 75, 89, 89, 88, 90, 99, 100. How does the stem-and-leaf plot show the distribution of these data? Construct the stem-and-leaf plot.

A. The lengths of the rows are similar to the heights of bars in a histogram; longer rows of data correspond to smaller frequencies. B. The lengths of the rows are similar to the widths of bars in a histogram; longer rows of data correspond to smaller frequencies. C. The lengths of the rows are similar to the widths of bars in a histogram; longer rows of data correspond to higher frequencies. D. The lengths of the rows are similar to the heights of bars in a histogram; longer rows of data correspond to higher frequencies.
A)Find the mean, median, mode, and range for the following data set 59,65,70,71,71,74,75,78,80,83,84,87,91,98,100 B)find the five number summary and draw a box plot. Briefly describe the shape and variation of the distribution. Explain your results.
Interpret the side-by-side (comparative) box-and-whisker plot using the five-number summary. Compare and discuss the typical annual starting salaries for each major. What conclusions can be drawn? Describe each distribution for accounting and marketing majors' annual starting salary.
THE DATA SHOW THE SCORES OF THE WINNING TEAMS IN THE ROSE BOWL. CONSTRUCT A FREQUENCY DISTRIBUTION FOR THE DATA USING A CLASS WIDTH OF 8. 28,34,37,34,17,38,21,20,41,38,24,20,45,21,26,38,48,32,41,38,21,38,34,46,17,22,20,22,45,20,45,24,28,23,17,17,27,14,23,18 FIND THE CLASS LIMITS. THE FIRST LOWER CLASS LIMIT IS 14.
3. Calculate the mean and median for the data representing the number of hours a random person spends online. Explain what this tells you about the shape of your distribution and which measure for the spread would be best? 15 12 6.2 7 5.5 2 4 5 10 11 7 6 4 7 01 5 3.2 4 10 6 2 10 1.5 5.1 6.4 8 14 3 2 4. Based on the distribution that you found in part 3, indicate whether the data is symmetric or skewed and then calculate the best measure for the spread of the distribution: Standard deviation or IQR. What information does this measure provide in terms of your data?
