Answer:
option (A) 251 phones
Explanation:
Data provided in the question:
Average quantities of prepaid cell phones used = 1500 per week
Standard deviation, s = 145
Lead time for their own brand of prepaid cell phones, L = 3 weeks
lot size = 350 phones
Safety stock = 500 phone
Now,
The standard deviation of demand during lead time will be
= Standard deviation × 
= 145 × √3
= 251.14 ≈ 251 phones
Hence,
The correct answer is option (A) 251 phones
Answer:
Confidence interval for the mean amount = 54+1.645*21/sqrt(16) =(62.64 , 45.36)
Explanation:
confidence interval = mean + z*, where z* is the upper (1-C)/2 critical value for the standard normal distribution.
z score for 90% confidence interval = 1.645
confidence interval for the mean amount = 54+1.645*21/sqrt(16) =(62.64 , 45.36)
Answer:
B) higher in the computer industry

Real GDP is totally based on the base year price level. This means that base year price level remains the same over all the periods. Therefore, Real GDP is generally not affected by the changes occur in the price level. Hence, it only includes the changes in output.
Nominal GDP takes into account the effect of changes in the price level. Therefore, it is affected by the changes in the price level and it is also measured in current U.S dollars. Hence, it doesn't show the true value of the goods and services produced in a given year.
A is the primary determinant of consumption and is usually measured in terms of current disposable income .
