Answer:

1 3/10 (SORRY IF ThIS IS WRONG)

Step-by-step explanation:

3/4 mile x 6 = 4 1/2

(we multiply by 6 because to get 60 minutes/1 hour you need to multiply 10 minutes by 6)

60/15=4

(we will multiply by 4 because we need that to get 1 hour)

4/5 x 4 = 3 1/5

4 1/2 - 3 1/5 = 4 5/10 - 3 2/10 (we do that so we can subtract easier)

4 5/10 - 3 2/10 = 1 3/10

Consider estimating a population proportion p. What is the most conservative sample size (erring on the large size) required in
just olya [345]

Answer:

The most conservative sample size is 2401.

Step-by-step explanation:

We are given the following in the question:

We are not given any approximation of s]ample proportion, thus,

\hat{p} = 0.5

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.5(1-0.5)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.5(1-0.5)}}{0.02}\\\\\sqrt{n}=49\\n = 2401

Thus, the most conservative sample size is 2401.
