Answer:
Cp = 1.667
Cpk = 1.25
The filling process will deliver the customer's specifications since Cp > 1 and Cpk > 1
Explanation:
Given data:
Customer Specification 3.98 4.02
Process Average 4.005
Process Standard Deviation 0.004
<u>Calculate the Cp and Cpk values</u>
Cp = Δ customer specification / ( 6 * std )
= (4.02 - 3.98 ) / ( 6 * 0.04 )
= 0.04 / 0.24 = 0.1667 + 1 = 1.667
Cpk ( upper ) = ( 4.02 - process average ) / ( 3* std )
= ( 4.02 - 4.005 ) / ( 3 * 0.004 ) = 1.25
Cpk ( lower ) = ( process average - 3.98 ) / ( 3 * std )
= ( 4.005 - 3.98 ) / ( 3 * 0.04 ) = 2.083
Cpk = minimum value of Cpk = 1.25
An appropriate choice of outdoor play equipment for a toddler play yard would be a small wooden playhouse. This is so because it helps them improve their health through using lots of energy which could be a good amount of exercise. Another reason is that it will improve their social skills. Since they will be talking and interacting with their playmates, their social skills will be properly honed. This will also help them become responsible because of the rules set on the playhouse.

b
Explanation:
Portfolio diversification is the process of holding different asset and security classes in order to minimise the non systemic risk of the portfolio
Correlation is a statistical measure used to measure the relationship that exists between two variables.
1. Positive correlation : it mean that the two variables move in the same direction. If one variable increases, the other variable also increases. It increases the risk of the portfolio
For example, there should be a positive correlation between quantity supplied and price
When there is a positive correlation, the graph of the variables is upward sloping
2. Negative correlation : it mean that the two variables move in different direction. If one variable increases, the other variable decreases. It decreases the risk of the portfolio
For example, there should be a negative correlation between quantity demanded and price
When there is a negative correlation, the graph of the variables is downward sloping
3. Zero correlation : there is no relationship between the variables. It decreases the risk of the portfolio
Answer:
C) Exports decrease, imports increase
Explanation:
If the US dollar appreciates, the US dollar has now more value per unit of foreign currency than before. For example, suppose that today 1 US dollar buys 0.8 Euro, and tomorrow, Europe is hit by a financial crisis, and the US dollar appreciates, and buys 1.2 Euro. The US dollar has appreciated, has become more expensive, becomes now more euros are needed to buy 1 US dollar.
When the US dollar gains value, domestic goods become more expensive compared to foreign goods, and this promotes imports, and reduces exports.
This is the reason why China keeps a depreciated currency: China is an export economy and the cheap Chinese currency makes exports cheaper, and imports more expensive.
