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 
Answer:
B) Make new loan totaling about $10 million.
Explanation:
Answer:
VC% = 73.5%
The New variable cost percentage of sales = 73.5%
Explanation:
Given;
New Fixed cost = $5.3 million
Total cost = $20 million
Total variable cost = $20 - $5.3 = $14.7 million
Variable cost percent=(total variable cost/total cost)×100%
VC% = (14.7/20) × 100%
VC% = 73.5%
