Answer: A.There is sufficient evidence to conclude that the mean price of a single-family home has increased from its level two years ago of $299,500
Explanation:
From the question, we are informed that according to the Federal Housing Finance Board, the mean price of a single-family home two years ago was $299,500 and that a real estate broker believes that due to recent credit crunch, the mean price has increased since then and the result is that the null hypothesis is not rejected.
The conclusion based on the results of the test is that since the null hypothesis has been rejected, it simply means that there are sufficient evidence that there has been an increase in the mean price since two years ago.
Therefore, option A is the correct answer.
An insurance policy with a higher premium most likely has a lower deductible
Answer:
112 customers per day
Explanation:
For computing the needed capacity requirement, first we have to find out the new utilization rate which is shown below:
Capacity cushion = 100% - average utilization rate
25% = 100% - average utilization rate
So, the average utilization rate is 75%
Now the needed capacity requirement is
Utilization rate = Average output rate ÷ Maximum capacity × 100
75% = 84 ÷ Maximum capacity × 100
So, the maximum capacity is 112 customers per day
We simply applied the above formula to determine the needed capacity requirement
Answer:
$427,011.92
Explanation:
We use the present value formula i.e to be shown in the attached spreadsheet
Given that,
Future value = $0
Rate of interest = 7.5%
NPER = 15 years
PMT = $45,000
The formula is shown below:
= -PV(Rate;NPER;PMT;FV;type)
And, in type we write the 1 instead of 0
So, after solving this, the present value is $427,011.92
