Answer:
$10,530
Step-by-step explanation:
I = Prt
P = 19500
r = 0.06
t = 9
I= 19500 x 0.06 x 9
I = 10530
Using the z-distribution, the confidence interval is given by: (11.95, 12.65).
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- is the standard deviation for the population.
In this problem, we have a 90% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 1.645.
The other parameters are given as follows:
Hence the bounds of the interval are:

Step-by-step explanation:
Answer:
Total cost= $4,445.28
Step-by-step explanation:
Giving the following formula:
Each side of a square classroom is 8 yards long.
The new carpet costs $79.38 per square yard.
<u>First, we need to calculate the total number of square yards needed:</u>
Square yards of the classrom= 8*8= 56
<u>Now, the total cost:</u>
Total cost= total square yards*unitary cost
Total cost= 56*79.38
Total cost= $4,445.28
