10. Critical Thinking The following data represent salaries, in thousands of dollars, for employees of asmall company. Notice that the data have been sorted in increasing order. 24 25 25 27 27 29 30 3535 35 36 38 38 39 39 40 40 40 45 45 45 45 47 52 52 52 58 59 59 61 61 67 68 68 68 250(a) Make a histogram using the class boundaries 23.5, 69.5, 115.5, 161.5, 207.5, 253.5.(b) Look at the last data value. Does it appear to be an outlier? Could this be the owner’s salary?(c) Eliminate the high salary of 250 thousand dollars. Make a new histogram using the classboundaries 23.5, 32.5, 41.5, 50.5, 59.5, 68.5. Does this histogram refl ect the salary distribution ofmost of the employees better than the histogram in part (a)?

You should have two separate plots: one for men and one for women. 6.  Why is it important to have the same stems for both plots, even though one plot has an empty stem? 7.  Comment on the distributions. What type on conclusions can you make about the heart rates of males and females? Do they appear to be very different?

The following data shows the results for 20 students in one of the post graduate unit.42 66 67 71 78 62 61 76 71 6761 64 61 54 83 63 68 69 81 53Based on the information given you are required to Compute the mean, median and mode.

A math professor is wondering if students today are better or worse than in the past. He has given the same final to this year's class that he gave ten years ago. Compute mean, median, and mode for both classes and write a paragraph summarizing the differences.

A flight travels daily from Pittsburgh to San Antonio. The following list gives the flight's arrival time (in minutes) relative to the scheduled arrival time for a selection of 10 days. (A negative number means the flight arrived that many minutes early.) -8, 9, -9,-10, 26, 36, -1, 11, 21, 23 Send data to calculator not (a) What is the median of this data set? If your answer. an integer, round your answer to one decimal place. (b) What is the mean of this data set? If your answer is not an integer, round your answer to one decimal place. Ozero modes (c) How many modes does the data set have, and what are their values? Indicate the number of modes by clicking in the appropriate circle, and then indicate the value(s) of the mode(s), if applicable. one mode: 0 two modes: and 5 2 Continue acer esc ! @ 3 $ 4 % 5 6 & 7
