Apol and Samson electronics are going head-to-head for the past decades. Though famous for mobile devices, both companies have big investments in the laptop and desktop computing industry. Apol with its eccentric and distinctive design ruled with its masterpieces (Makbook and iMak) which are exceptionally stylish. Samsung on the other hand launches its top-of-the-line Notebook Pro and Galasi series. With tight competition and a high margin at stake, exact measurements are badly needed to be ahead of the competition. Kristine a methods and measurements analyst from the Electronic Division of Samson needs to develop a time standard for the task of assembling a computer mouse. In a preliminary study, she observed one of her workers perform this task six times with the following results:

Observation	1	2	3	4	5	6
Time(Seconds)	46	38	40	34	42	40

1. How many observations should be made if she wants to be 86.64 percent confident that the maximum error in the observed time is .5 second? Assume that the standard deviation of the task time is four seconds.

2. What is the standard time for this task if the employee worked at a 20 percent faster pace than average and an allowance of 25 percent of the workday is used?
