Below are the times (in days) it takes for a sample of 16 customers from Jack's computer store to pay their invoices. 19, 15, 43, 39, 35, 31, 27, 22, 18, 14, 30, 30, 26, 26, 26, 21 Send data to calculator Draw the histogram for these data using an initial class boundary of 13.5 and a class width of 7. Note that you can add or remove classes from the figure. each class with its endpoints. Frequency 7+ 6- 5- 4- 3- 2 0 0 0- 0 Time (in days) 0 0 0:00 00:0 X 5

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 9, maximum = 83, 6 classes The class width is 12. Choose the correct lower class limits below. O A. 9, 21, 35, 47, 60, 74 O B. 22, 34, 48, 61, 74, 86 O C. 21, 34, 48, 60, 73, 86 O D. 9, 22, 35, 48, 61, 74 Choose the correct upper class limits below. A. 21, 34, 48, 61, 73, 86 O B. 22, 35, 48, 61, 74, 86 O C. 22, 35, 47, 60, 74, 86 O D. 21, 34, 47, 60, 73, 86

For the data set:   5,  11,  1,  2,  27,  30,  15  we would have the middle number being 2.  Why isn’t 2 the median here – what did we forget to do or what is missing?

please help.
