A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use of a ruler, square
, and portable electric saw to mark and cut the "notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an airconditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available. Observation: 1 2 3 4 5 Task time (seconds): 82 74 80 83 76 a. What is the actual average time for this task? b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers? c. What is standard time for this task if allowances sum to 14%? d. If the analyst then thought more carefully about his experiment and decided that the allowances needed to be increased to match the real (outside, not air-conditioned) work environment, and that the proper allowance was not 14% but 20%, what is the revised standard time?

Answer:
Explanation:
From the information given, by applying Kepler's 3rd law,
where;
T = period
a = semi major axis
T = 356 days (for earth)
a = 1 AU = 1.496
Therefore,
c = 3.9791
However, if the body in the solar system has a period of 10.759.22 days, then, a =?
∴
a = 1.4275
However, the velocity for a perihelion = 10.18 km/s
Using the formula
to calculate the radius, we have:
G =
M =
r = perihelion
Similarly, the perihelion is expressed by the equation,
r = a(1 - e)
where ;
e= eccentricity
∴
e ( eccentricity) = 0.0533
Aphelion radius in natural miles, r = a( 1+ e)
to nautical miles, we have:
radius of aphelion nautical miles
In respect to the value of a( i.e
the body of the solar system is Saturn
