Answer:
Loss section
Step-by-step explanation:
Given
-- cost
-- revenue
Required
Determine where n = 150 is
To do this, we substitute 150 for n in the given functions
The above shows that the revenue is greater than cost for n = 150.
This implies that, n = 15o is the loss section.
Part a)
The simple random sample of size n=36 is obtained from a population with
and
The sampling distribution of the sample means has a mean that is equal to mean of the population the sample has been drawn from.
Therefore the sampling distribution has a mean of
The standard error of the means becomes the standard deviation of the sampling distribution.
Part b) We want to find
We need to convert to z-score.
Part c)
We want to find
We convert to z-score and use the normal distribution table to find the corresponding area.
Part d)
We want to find :
We convert to z-scores and again use the standard normal distribution table.
