C. Provide objective evidence that a transaction has taken place.
Answer:
Explanation:
A:
Number of contracts required:
= (0-1.2)×36,000,000÷(900×$250)
= -192
Since negative value, short 192 contracts.
B:
= (0.9 - 1.2)×36,000,000÷(900×$250)
= -48
Since negative value, short 48 contracts.
C:
= (1.8 - 1.2)×36,000,000÷(900×$250)
= 96
Since positive value, long 48 contracts.
Answer: Option B
Explanation: Safeguarding inventory refers to keeping proper records of inventory and protecting it from any kind of damage that may result in loss to the organisation.
The main objective behind safeguarding inventory is to minimize loss of the organisation that is keeping it.
In the given case, second option is the purchase return and it could not be considered a default of the purchaser of inventory.
Hence from the above we can conclude that the correct option is B.
Answer:
Sample size is 16
Mean 4
Standard deviation of the sample is 0.3.
Explanation
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
In this problem, we have that:
The population has a mean of four hours, with a standard deviation of 1.2 hours. The sample is the 16 of the employees.
So
The sample size is 16, so 
The mean of the sample is the same as the population mean, so 
.
The standard deviation of the sample is
