Question

a) The time for first set of uniform was 3 hours, the time for 2nd set was 2.5 hours. What is the learning Curve? Show your workings clearly.

Answer #1

Learning curves are the curves which represent the fact that with an increase in the number of times an activity is done, the time taken to complete it reduces with every repitition. This maybe due to increased efficiency and increased learning of the task.

A learning curve graph usually shows laborhours/unit w.r.t. no. of units produced.

It is a a negative exponential curve showing that time required to produce a unit decreases, with an increased production in units.

This is the reason that 1st time we produce a good, it takes 3 hours, but the secong time, it takes only 2.5 hrs.

Following is the graph for the learning curve.

A time standard was set at 5.50 hours per unit based on the
100th unit produced (i.e. ). If the task follows a 90 percent
learning curve, what would the expected time be for the 200th,
300th, and 400 the units? (you need to start with the book’s method
using the tables to find the learning rate)

The cumulative average labor hours to assemble the first five
units of product A was 14.541 hours. If the learning curve, based
on the previous experience with similar products, is 85%, what is
the estimated time (labor hours) that will be required to assemble
the 22th unit?

A job has a 90% learning curve. If the first unit took 10 hours
to complete, the fifth unit should take roughly how many hours?

We dropped two
objects with the
time difference of
3 seconds (the 2nd
one was released
3(s) after the
first one). Their
maximum distance on
their free fall is
75 (m). What
is the height h
that the objects
were released from?
(to make life
easier g=10 m/s^2)

2nd time posting first answer to this part of the question was
wrong:
The Economic Policy Institute periodically issues reports on
workers' wages. Suppose the institute reported that mean wages for
male college graduates were $37.39 per hour and for female college
graduates were $27.83 per hour in 2017. Assume the standard
deviation for male graduates is $4.60 and for female graduates it
is $4.10. (Round your answers to four decimal places.)

Let S3 be the set of permutations of 3 elements. Define a
uniform probability distribution on S3. Compute the probability of
derangements.

An oil production project involving 10 oil wells has been
approved. The estimated number of engineering hours required to set
up the first oil well is 135. Assuming a 95% learning curve, what
is the cumulative hours for setting up the first three wells? Round
your answer to integer.

Given the data set with t values in the first column and y
values in the second column, write a script file that:
-Curve fits the given data set with an appropriate polynomial
function
-Outputs the R2 value of the appropriate fit along
with the values of the polynomial order higher and lower (ex. If
you choose a 2nd order fit, display the R2
value for first, second, and third order fits.)
- Estimate the value of the data at...

LEARNING CURVE
There are 2 firms: Company A and Company B.
1. Company A took 150 hours to produce its first
unit.
This month it wants to product 500 units.
Using 80% learning curve, how many hours will it take to produce
those 500 units?
2. Comany B also produced 500 units.
However, it took B only 50 hours to produce its first unit.
What was was B's learning curve?
Can someone show me step by step please

It took a Wisconsin shipyard 125,000 labor-hours to produce the
first of several tugboats that you expect to purchase for your
shipping company, Great Lakes, Inc. Boats 2 and 3 have been
produced by the company with a learning factor of 85%. At $40 per
hour, what should you, as purchasing agent, expect to pay for the
fourth unit?
