A auto manufacturer claims that one of its car brands has mean MPG (miles per gallon) rating of 40 on the highway. Identify Type I error for this claim.

a. Fail to reject the claim that mean is 40 MPG when it is actually 40 MPG.
b. Fail to reject the claim that mean is 40 MPG when it is actually not 40 MPG.
c. Reject the claim that mean is 40 MPG when it is actually not 40 MPG.
d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.

Answers

Answer:

d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.

Step-by-step explanation:

The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.

In the scenario above :

The null hypothesis (H0) : mean = 40

Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.

On the other hand, the type 2 error occurs when a null which is false is not rejected.

Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.

First solve the second equation. Replace g (2) into that equation which just means replace 2 in the place of x. You should get f (3). Then, replace f (3) in the first equation which just means replace 3 in the x's.

When evaluting an expression, is it easier to combine terms first or substitute values first? PLSSSS ANSWERRR ILL GIVE BRAINLIEST

Answers

Answer:

What do you mean by combining terms?

If you have an equation like y=3(2+x), then you would need to substitute for x before you combined the terms "2" and "x"

If you mean combine LIKE terms then I would do that first, if not then I would substitute the values

Please find measure of angle s. PLEASE HELP FAST!!

Answers

Answer:

Step-by-step explanation:

15x-31 = 9x+11

6x-31 = 11

6x = 42

x = 7

15x -31 + 9x + 11 + s = 180

15(7) -31 + 9(7) + 11 + s = 180

105 - 31 + 63 + 11 + s = 180

Answers

Answer:

The amount of time that is spent downloading internet files is a continuous measurement and is not discrete, because it will always follow the same length of time that is estimated to download, but due to changes of internet WiFi connectivity and other background programs this can all affect the speed of the computer programs responsible for downloading the files.

Answer:

(7 -24√3)/50 = 0.14 -0.48√3

Step-by-step explanation:

Sine is negative and cosine is positive in the 4th quadrant, so ...

sin(α) = -√(1 -cos(α)²) = -√(1 -576/625) = -7/25

Then the cosine of the angle sum is ...

cos(α +5π/6) = cos(α)cos(5π/6) -sin(α)sin(5π/6)

= (24/25)(-√3/2) -(-7/25)(1/2)

= (7 -24√3)/50 = 0.14 -0.48√3

Suppose the graph of a cubic polynomial function
has the same zeroes and passes through the
coordinate (0, -5).
Describe the steps for writing the equation of this
cubic polynomial function.
DONE

Answers

Answer:

Use the zeroes to determine the roots.

Write the polynomial as a product of the leading coefficient, a, and the factors, where each factor is x minus a root.

Use the y-intercept (0, –5) to solve for the leading coefficient.

Substitute the leading coefficient into the polynomial function for a and simplify.

Which fraction is equivalent to 2/3 explain

Answers

Answer:

4/6, 8/12, 20/30

Step-by-step explanation:

They are equivalent to 2/3, because they can all be simplified to 2/3.

For example, 2 x 2 = 4 and 2 x 3 = 6; this gives me 4/6. I multiplied 2/3 by 2/2.

SO it can also be 2/3 = 4/6= 6/9 = 8/12 = 10/15 = 12/15 = 15/18 = 18/21 = 21/24 etc.
