The mean monthly gasoline bill for one household is greater than $140. if a hypothesis test is performed, how should you interpret a decision that fails to reject the null hypothesis?
a. there is sufficient evidence to reject the claim mu > $140.
b. there is not sufficient evidence to support the claim mu > $140.
c. there is sufficient evidence to support the claim mu > $140.
d. there is not sufficient evidence to reject the claim mu > $140.

C. There is sufficient evidence to support the claim .

Step-by-step explanation:

Given (claim) :The mean monthly gasoline bill for one household is greater than $140.

Let be the population mean.

Then, the set of hypothesis for this claim will be:-

If a hypothesis test is performed , then to interpret a decision that fails to reject the null hypothesis we says that there is sufficient evidence to support the claim

step-by-step explanation:

the answer is 89 d

i took the test

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
