Answer:
The number of units to be ordered is 961.
Step-by-step explanation:
The optimum demand is given as
From the data
Daily demand is given as =50
Standard deviation is given as
The Lead time is given as L=10 days
The Revier time is given as R=5 days
Initial values given as I=60 units
The confidence level is given as 99% so z is calculated using the NORMSINV() function as NORMSINV(0.99). The value of z is 2.33
Now the standard deviation in terms of the Lead and Review time is given as
Substituting the values in the formula as
So the number of units to be ordered is 961.
Answer:
We are 90% confident that the population mean number of children per adult is between 1.80 and 1.94.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 1.87 - 0.07 = 1.80 children
The upper end of the interval is the sample mean added to M. So it is 1.87 + 0.07 = 1.94 children.
We are 90% confident that the population mean number of children per adult is between 1.80 and 1.94.
