Please help this is due by today and I need this to get a good grade in my class!! During the Swine Flu pandemic, a study found that if someone in your family contracted the Swine Flu, you had 1 in 8 chance of also contracting the disease. A random sample of 876 people with family members who had the flu found 129 to be positive.
Calculate a 90% confidence interval for the proportion of people who contract Swine Flu after a family member does.
Is there statistical evidence that the proportion of family members who contract the flu is different from the 1 in 8 chance as stated in the study?

109 trust me

step-by-step explanation:

-1/2 +2

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

hey pal. the answer is b plz mark as brainliest
