Based on the nielsen ratings, the local cbs affiliate claims its 11 p. m. newscast reaches 41% of the viewing audience in the area. in a survey of 100 viewers, 36% indicated that they watch the late evening news on this local cbs station.

what is your decision if α = 0.01?

a. fail to reject the null hypothesis.

b. reject the null hypothesis and conclude the newscast does not reach 41% of the audience.

c. fail to reject the alternate and conclude the newscast does not reach 41% of the audience.

d. reject the alternate and conclude the newscast reaches about 41% of the audience.

a. Fail to reject the null hypothesis.

Step-by-step explanation:

Here we test the claim that proportion of reachers is really 41%

(Two tailed test at 1% significance level)

Observed proportion = 0.36

Sample size n = 100

Std error of proportion =

p difference = 0.36-0.41 =- 0.05

Test statistic Z = p diff/std error =-1.0166

p value=0.286

Since p >0.01 we accept null hypothesis.

a. Fail to reject the null hypothesis.

dude thats to long figure it

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
