The unit improvement factor for a 60% learning curve at 25 units is 0.0933.The first and second timings of a person doing a job are 5 minutes and 3 minutes respectively.Which of the below is the learning-adjusted time estimate for unit number 25?

When plotted on a graph,the learning curve can't be expressed as logarithm.

You have just timed a person doing a hair cut for the first time.It took 50 minutes.What unit improvement factor learning curve would you use if the person took 35 minutes on the second hair cut?

An assumption of learning curve theory is which of the following?

On a learning curve plot,the time per unit is usually displayed on the vertical axis.

learning curve is a line displaying the way unit production time decreases as time passes.

With an 80 percent unit improvement factor learning curve and an initial time of 100 minutes to do a job,at what number of repetitions will the job take less than 50 minutes?

company can produce a small lot of products the first time at a cost of $3,000.If their 65 percent Learning Curve allows them to reduce their costs on each lot,what is the cost of producing the 20^th lot?

Which of the following computational methods are used to calculate learning curve statistics?

An assumption of learning curve theory is which of the following?

learning curve is a line displaying the relationship between unit production time and the cumulative number of units produced.

If a person performing a task has been achieving a 95 percent learning curve and you know that the task will end after the 100^th unit,the last unit produced will take 71.12 percent as much time as the first unit.

learning curve shows the increase in time required for each successive unit completed.

At the 10^th repetition of job it is timed at 100 minutes.If the learning curve for this job is 80 percent,what is the estimated time for the 100^th repetition of this job?

Learning curves can be applied to individuals and to organizations.

You time someone completing a single task the first time at 100 minutes and the second time they do the task it takes 90 minutes.You should use a 90 percent learning curve to estimate the length of time this worker will take to complete this task in the future.

If a person performing a task has been achieving an 85 percent learning curve and if it took 1 minute to produce the first unit,the total time to produce 1,000 units will be 437.5 minutes.

An assumption of learning curves is that the time required to complete a unit will decrease at an increasing rate as the cumulative number of units completed increases.
