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.
One hundred students in a statistics course kept track of the time they spent on social media over the weekend. Each student recorded his or her time rounded to the nearest minute, so each observation is a whole number. The data are presented in the form of a frequency histogram. 26 25- 20 20- 16 15 14 12 10- 120 150 I80 210 30 Minutes on social media Each interval on the histogram contains the left endpoint, except for the last bar, which contains both the left and right endpoints. Give the lower and upper bound for the median number of minutes spent on social media over the weekend by the students enrolled in the class. The lower bound is the largest number that is less than or equal to the median, and the upper bound is the smallest number that is greater than or equal to the median. lower bound = 60 upper bound = 85 Kouanbasg
