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.
a) Find a point estimate for the proportion of people who would die if
infected with the bird flu.
b) Construct a 90% confidence interval for the proportion of cases that would be
expected to result in death if a pandemic occurred.

is this part of a question or something

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
