in a random sample 70 people it was found that 44 of them were fans for the New York Yankees what is the margin of error for a true proportion of all individuals who are fans of the New York Yankees

The general formula for the margin of error would be:

z * √[p (1-p) ÷ n]

where:

z = values for selected confidence level

p = sample proportion

n = sample size

Since the confidence level is not given, we can only solve for the

√[p (1-p) ÷ n]  part.

p = 44/70

n = 70

√[44/70 (1 - (44/70) ÷ 70]

√[0.6286 (0.3714)] ÷ 70

√0.2335 ÷ 70

√0.0033357 = 0.05775 or 0.058 Choice B.

40% off the regular price is the correct answer.

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
