5. The female students in an undergraduate engineering core course at UH self-reported their heights to the nearest inch. The data is as follows. 62 64 61 67 65 68 61 65 60 65 64 63 59 68 64 66 68 69 65 67 62 66 68 67 66 65 69 65 69 65 67 67 65 63 64 67 65 First construct the frequency distribution Table like Table 6-4 on Page 213 of textbook where you only need to specify the classes/bins, frequency info. Then using the table to create the histogram; here let the height of rectangle (for each bin) equal to the frequency instead of relative frequency in your histogram even though you can also set the height as the relative frequency. Hint: create the frequency distribution table by hand, but you can create the histogram in Excel and insert the result as a figure.

A large company's human resources manager undertakes a research that examines the employment records of 500 employees for absenteeism over the previous year. The data is organised into a frequency distribution by the business researcher conducting the study to assist the human resources manager in analysing the data. This graphs show the frequency distribution. Class interval Frequency 0 – 1 218 2 – 3 207 4 – 5 56 6 – 7 11 8 – 9 8 List three specific uses of cumulative frequencies in business. Display a relative frequency histogram and relative frequency polygon for these data. Find mean, median, mode, variance and standard deviation for grouped data.
