A public health official is planning for the supply of influenza vaccine needed for the upcoming flu season. She took a poll of 280 local citizens and found that only 113 said they would be vaccinated.
1. Assuming that the population of the city is very large, construct the 91% confidence interval for the true proportion of people who plan to get the vaccine and provide the lower and upper bound of the confidence interval.
2. Now, assume that the town’s population is 1,400. Construct the 91% confidence interval and provide the lower and upper bound of the confidence interval
3. How would you be wrong if the town’s population was in fact 1,400 but you computed the confidence interval not taking into account the finite population correction factor? Explain.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

where is the gragh

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
