Answer:
A) 1.111
B) 0.889
Explanation:
given data :
outer diameter of connecting rods = 1 ± 0.01 inch
sample mean outer diameter = 1.002 inches
standard deviation = 0.003 inches
A) Calculating the Cp of the process
mean = 1.002
Standard deviation = 0.003
LSL = 1 - 0.01 = 0.99
USL = 1 + 0.01 = 1.01
= 
= 1.111
B) calculate Cpk
mean = 1.002, LSL = 0.99, USL = 1.01 , deviation = 0.003
![Cpk = min[\frac{mean-LSL}{3* deviation} , \frac{USL- mean}{3*deviation} ]](https://tex.z-dn.net/?f=Cpk%20%3D%20min%5B%5Cfrac%7Bmean-LSL%7D%7B3%2A%20deviation%7D%20%2C%20%5Cfrac%7BUSL-%20mean%7D%7B3%2Adeviation%7D%20%5D)
= min [(0.012/0.009) , (0.008/0.009) ]
= min [ 1.333, 0.889 ]
hence Cpk = 0.889
Answer: I decreases; II decreases; III decreases
Explanation:
Debt Covenants becoming more restrictive means that less people want to borrow money. This shifts the demand curve to the left and this Decreases interest rates.
The Fed increasing money supply means that there is more money in the economy. This shifts the supply curve to the right thus having the effect of reducing Interests rates as there is more money available for loans.
Total Household Wealth increasing means that Households have less of an incentive to borrow money. This reduces the demand for interest rates so interest rates decrease.
Answer:
recognized on March 31 after the delivery of the equipment
Explanation:
Revenue is recognized once the recognition criteria is met. These criteria includes;
- the cost of the item sold can be measured reliably
- the items has been delivered or the service has been rendered
Given that the contract specified a delivery date of March 1.
The equipment was not delivered until March 31 and as such, the revenue for the contract should be recognized on March 31 after the delivery of the equipment.
