Acme Industries has implemented a new website for employees to enter their weekly hours (e.g., start time, end time, sick hours, vacation hours, holiday hours, family leave hours). Upon clicking Save, the system checks the validity of the entries and points the user to correct any errors or omissions before saving the data. To evaluate the efficiency of this new website, the system journals the access time (in seconds) indicating how long it took for each employee to file their daily entries. A manager will assess the mean access times starting at the initial launch of the website (Week1), and continue to gather data for the next week (Week2).
