Using a random sample of 5613 TV households, Acme Media Statistics found that 25.1 % watched the final episode of "When Will it End question mark" a. Find the margin of error in this percent.

b. Write a statement about the percentage of TV households in the population who tuned into the final episode of "When Will it End question mark"

Margin of Error (MOE) is a function of the critical value. We will choose a confidential interval of 95 %.

Solution is:

a) MOE = 0,011

b) We can affirm with 95 % of confidence that the porcentage of TV households in the population watching th final  episode of " When ...

would be between  25,1 - 0,011  and  25,1 + 0,011

In our question we got:

Sample size    n = 5613

p = 25.1 %    ( positive events expressed as porcentage )

q = 1 - p     q = 1 - 0,251    q = 0,749

According to the size of the sample, and the fact that

q×n    and   p×n   are both    q×n > 10   p×n > 10

We are in condition to apply the approximation of the binomial distribution to normal distribution and use table z scores

CI   = 95 %    then  confidence level   α = 5 %    α/2 = 0,025  and fom z-table we get the critical value

z(c) = 1,96

Now to find MOE

MOE = z(c)×√(p×q/n)  ⇒ MOE = 1,96 × √ ( 0,251×0,749)5613

MOE = 1,96 × 0,005787

MOE = 0,011

If Confidential Interval is 95%

± 1.13432%

between 23.966% and 26.234% households in the population who tuned into the final episode of "When Will it End question mark"

Step-by-step explanation:

Given that:

Sample size (n). = 5613

Proportion (p) = 25.1% = 0.251

Margin of Error can be obtained using :

MOE = z * √p * (1 - p) / √n

Zscore at 95% confidence interval = 1.96

1 - p = 1 - 0.251 = 0.749

Hence,

Margin of Error :

1.96 * √0.251 * 0.749 / √5613

1.96 * (0.4335885 / 74.919957)

= 0.0113432

= ± (0.0113432) * 100%

= ± 1.13432%

B.) between (25.1 - 1.134)% = 23.966% and 25.1 + 1.134)% = 26.234% households in the population who tuned into the final episode of "When Will it End question mark"

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

answer: get a conversion sheet out i dont know the exact measurments
