As a potential worldwide pandemic, avian influenza H5N1 (commonly called the bird flu) poses a serious health risk. As of January 24, 2012, there have been 583 human cases of this virus in the world. Of these cases, 344 have resulted in death. Consider the outcomes of these cases as a random sample of all possible outcomes.

Find a point estimate for the proportion of people who would die if infected with the bird flu.

Construct a 90% confidence interval for the proportion of cases that would be expected to result in death if a pandemic occurred.

Interpret the confidence interval.

A

Step-by-step explanation:

We take the percentage raise and convert to decimal by dividing by 100. Then multiply this with the salary before raise. This will give us the "raise amount".

Then we will add up all of the "raises" of 3 employees to get our answer.

Jane = 4/100 = 0.04

0.04*41,500 = 1660

John = 4.5/100 = 0.045

0.045 * 44,100 = 1984.5

Jack = 3/100 = 0.03

0.03 * 39,600 = 1188

Sum of all 3 raises:

1660 + 1984.5 + 1188 = $4832.5

From the answer choices, A is the closest, $4833
