Answer:

6.5×10'3=6,500.

5.5×10'5=550,000

1.1×10'3=1,100

so as u can see the second number is greater

by 548,900

An environmentalist wants to find out the fraction of oil tankers that have spills each month. Suppose a sample of 836 tankers i

Alexxandr [17]

Answer:

<em>The 99% confidence interval for the population proportion of oil tankers that have spills each month.</em>

<em>(0.6489 , 0.7311)</em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given sample size 'n' = 836

Suppose a sample of 836 tankers is drawn. Of these ships, 577 did not have spills.

sample proportion

$p^{-} = \frac{x}{n} = \frac{577}{836} = 0.690$

<em>The 99% confidence interval for the population proportion is determined by</em>

<em></em> $(p^{-} - Z_{0.01} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.01} \sqrt{\frac{p(1-p)}{n} })$ <em></em>

<u><em>Step(ii)</em></u><em>:-</em>

<em>The Z- value = 2.576</em>

<em></em> $(0.690 - 2.576 \sqrt{\frac{0.690(1-0.690)}{836} } , 0.690 + 2.576 \sqrt{\frac{0.690(1-0.690)}{836} })$ <em></em>

<em>On calculation , we get</em>

<em>(0.690 - 0.0411 , 0.690 + 0.0411)</em>

<em>(0.6489 , 0.7311)</em>

<u><em>Final answer</em></u><em>:-</em>

<em>The 99% confidence interval for the population proportion of oil tankers that have spills each month.</em>

<em>(0.6489 , 0.7311)</em>

<em></em>
