A manager oversees N = 33 employees that complete case files each day. Some of her employees are working in the office (n = 15) while the others are remotely working at home (n = 18). She would like to track how many case files employees complete. The following are frequency distribution tables for both cases (X). groups of employees indicating how many employees (f) were able to complete a certain number of Office Workers Remote Workers X X 20 20 19 19 18 18 17 17 16 16 HHOUNHNUP 15 15 HOOHOA 14 13 13 12 1225. Which is the best description of the shape of the distribution for the office workers? 26. Which is the best description of the shape of the distribution for the remote workers? 27. Calculate the sample variance, s2, for the office workers. 28. Calculate the sample standard deviation, s, for the office workers. 29. Calculate the sample variance, s2, for the remote workers. 30. Calculate the sample standard deviation, s, for the remote workers. 31. Calculate the Grand Mean to determine the average number of case files completed for all employees
