An automobile manufacturer claims that its jeep has a 59.8 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this jeep since it is believed that the jeep has an incorrect manufacturer's MPG rating. After testing 160 jeeps, they found a mean MPG of 59.7. Assume the standard deviation is known to be 1.3. A level of significance of 0.02 will be used. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.
Answer:
The value of the test statistic is -0.97
Step-by-step explanation:
This test is two tailed test.
Null and Alternative hypothesis is as follow
Null Hypothesis is used when it is assumed that there is no significant difference between the values.
Null Hypothesis = [tex]H_{0}[/tex] = [tex]\mu =[/tex] 59.8
The Alternative hypothesis is the alternative of the Null Hypothesis. It is an experimental technique that is used when it is assumed that there is some difference
Alternative Hypothesis = [tex]H_{a}[/tex] = [tex]\mu \neq[/tex] 59.8
Test statistcs is z
The value of test statistics can be calculated using the following formula
Test Statistics [tex]= (\bar x - \mu ) / \sigma / \sqrt n[/tex]
Test Statistics [tex]= (59.7-59.8) / 1.3 / \sqrt 160[/tex]
Test Statistics = -0.97

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining to be paid. The graduate makes regular payments of $8,000 each year. The graph shows the sequence. f(x)=?
Answer:
The equation is: [tex]f(x) = 52000 - 8000x[/tex]
Step-by-step explanation:
Given
Initial = 52000
Rate = 8000 each year
Required
Determine the equation of the graph
The equation can be determined using.
[tex]Amount = Initial - Rate* Years[/tex]
We used minus (-) because, the amount reduces as the student pays.
Let
[tex]y = Amount[/tex]
[tex]x = Years[/tex]
So, we have:
[tex]y = Initial - Rate * x[/tex]
Substitute values for Initial and Rate
[tex]y = 52000 - 8000 * x[/tex]
[tex]y = 52000 - 8000x[/tex]
Express as a function:
[tex]f(x) = 52000 - 8000x[/tex]

5x-(x-18)=6-2(x+15) Help!
Answer:
Step-by-step explanation:
5x-(x-18)=6-2(x+15)
5x-x+18=6-2x-30
6x=-42
x=-7
The equivalent value of the expression is x = -7
Given data ,
Let the equation be represented as A
Now , the value of A is
5x - ( x - 18 ) = 6 - 2 ( x + 15 )
On simplifying the equation , we get
5x - ( x - 18 ) = 6 - 2 ( x + 15 )
So , the left hand side of the equation is equated to the right hand side by the value of 6 - 2 ( x + 15 )
Opening the parenthesis on both sides , we get
5x - x + 18 = 6 - 2x - 30
From the distributive property , we get
5x - x + 18 = 6 - 2x - 30
On further simplification , we get
4x + 18 = -2x - 24
Adding 2x on both sides , we get
6x + 18 = -24
Subtracting 18 on both sides , we get
6x = -24 - 18
6x = -42
Divide by 6 on both sides , we get
x = -42/6
x = -7
Therefore , the value of x = -7
Hence , the expression is x = -7

Which of the following is a right triangle?
A.
a triangle with sides measuring 13, 15, and 19
B.
a triangle with sides measuring 17, 25, and 36
C.
a triangle with sides measuring 20, 21, and 29
D.
a triangle with sides measuring 18, 23, and 41
Answer:
Step-by-step explanation:
the right choice is C
you use c^2=a^2+b^2
where the largest side is the hypotenuse
Answer:
C.
a triangle with sides measuring 20, 21, and 29
Step-by-step explanation:
As, √(20)²+(21)² = √400+441 = √841 = 29
The longest side is taken as the hypotenuse. So 29 is the hypotenuse. Which by using Pythagoras' theorem gives us 29 ( h=√b²+p² )

A store manager designs a new accounting system that will be cost effective if the mean monthly charge account balance is more than $50. A sample of 100 accounts is randomly selected. The sample mean balance is $56 and the sample standard deviation is $25.a.Find the t-statistic for a hypothesis test that is designed to answer the question.
Answer:
The t-statistic for a hypothesis test that is designed to answer the question is 2.4.
Step-by-step explanation:
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the saple and n is the size of the sample.
A store manager designs a new accounting system that will be cost effective if the mean monthly charge account balance is more than $50.
This means that [tex]\mu = 50[/tex]
A sample of 100 accounts is randomly selected. The sample mean balance is $56 and the sample standard deviation is $25.
This means that [tex]X = 56, s = 25, n = 100[/tex]. So
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]
[tex]t = \frac{56 - 50}{\frac{25}{\sqrt{10}}[/tex]
[tex]t = \frac{6}{2.5}[/tex]
[tex]t = 2.4[/tex]
The t-statistic for a hypothesis test that is designed to answer the question is 2.4.
