9514 1404 393

Answer:

9/160
9/160

Step-by-step explanation:

Divide each number in the ratio by their greatest common divisor.

4500 : 80000 = (4500/500) : (80000/500) = 9 : 160

8100 : 144000 = (8100/900) : (144000/900) = 9 : 160

In a survey of 2957 adults, 1455 say hey have started paying bills online in the least year construct a 99% confidence interval

Vikki [24]

Answer: 0.49 ± 0.0237

Step-by-step explanation: A interval of a 99% confidence interval for the population proportion can be found by:

$p_{hat}$ ± z. $\sqrt{\frac{p_{hat}(1-p_{hat})}{n} }$

$p_{hat}$ is the proportion:

$p_{hat}$ = $\frac{1455}{2957}$

$p_{hat}$ = 0.49

For a 99% confidence interval, z = 2.576:

0.49 ± 2.576. $\sqrt{\frac{0.49(1-0.49)}{2957} }$

0.49 ± 2.576. $\sqrt{\frac{0.49*0.51}{2957} }$

0.49 ± 2.576.(0.0092)

0.49 ± 0.0237

For a <u>99% confidence interval</u>, the proportion will be between 0.4663 and 0.5137 or 0.49 ± 0.0237
