As a manager, it is important to know how many employees you need to perform a specific task. In order to determine the amount of employees you will need to determine how long it takes to perform a task.

Complete the work measurement and productivity problems.

$1.$ Based on a productivity log$,$ a coder completed $22$ charts during a $7\mathrm{.}5-$hour workday. How many charts did he code per hour? Round to the nearest whole number.

$2.$ Based on work measurement studies on your coders, you find that $20\%$ of their time is spent querying physicians about missing or unclear documentation. If your coders work a $7\mathrm{.}5-$hour day, how many minutes do they spend per day querying physicians?

$3.$ A coding supervisor reviewed the productivity logs of four recently$-$hired coders after one month $($coders work $5$ days per week.$)$ The supervisor compiled a report, shown below. Complete analysis of the report and determine which employee will require additional training or assistance in order to meet the coding standard.

$4.$ The release of information $($ROI$)$ processing unit is expected to respond to routine requests for information within five $(5)$ working days of receipt. Work measurement data collected for one month reveals the following:

Total routine requests received: $200$

Requests responded to in $6$ days: $100$

Requests responded to in $2$ days: $100$

What is the average turnaround time for routine requests in the ROI unit? What is the performance variance from the standard of $5$ days? Explain your answer.
