Asimple random sample of 3,500 people age 18 or over is taken in a large town to estimate the percentage of people (age 18 and over in that town) who read newspapers. it turns out that 2,487 people in the sample are newspaper readers. the population percentage is estimated as

2,487/3,500 x 100% ≈ 71%

the standard error is estimated as 0.8 of 1%, because

3,500 x √0.71x0.29 ≈ 27, 27/3,500 x 100% ≈ 0.8 of 1 %

(a) is 0.8 of 1% the right se? answer yes or no, and explain.

(b) 71% ± 1.6% is a for the fill in the blanks and explain.

you already gave the answer

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
