Using the t-distribution, it is found that the value of the test statistic is t = -87.3.
At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:

At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:
.
We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
The values of the <em>parameters </em>are:
.
Hence, the value of the <em>test statistic</em> is:

I found the pie chart that should accompany this problem, as well as, the choices of answer for this problem.
A $16
B $18
C $20
D $22
E $24
Total production from crude oil: 60 million barrels
Gasoline production: 34%
60 million barrels * 34% = 20,400,000
Total income: $408 million
408,000,000 / 20,400,000 = $20 choice C.
I=P*R*T
I - Interest
P - Principal (how much you invest) - $1025
Rate - Interest rate - 6.5% = . 065
T - Time - 5 years
I = 1025*.065*5
The interest is $333.13 (333.125 rounded)
The ending balance is interest+principal
$333.13+$1025=$1358.13
Ending Balance = $1,358.13
