Standard Time ( 5 marks)

A large cable company received a shipment of audio video cables with the wrong connectors. The error was made by the cable companys specifications provided to the overseas supplier. The operations manager calculates that it would be cheaper to manually change the connectors rather than the supplier re-doing or fixing the cables. The manager observes the first set of workers pulled aside to change the cables and from these observations will set a standard time. The observations are as follows for workers to each change the connectors on sets of 20 cables.

Observation		Time (min)
1		7.17
2		7.23
3		6.98
4		7.05
5		7.54
6		7.33
7		7.11
8		7.27
9		7.09
10		6.99

The manager will use a performance rating factor of .95 and an allowance factor of .04.
