Suppose a poll conducted at a certain college during their most recent spring semester asked 695 college students whether or not a privately owned dining hall should be allowed on campus. The response "Yes, it should" was selected by 38% of the respondents.

(a) Suppose the researchers who conducted the poll reported "For results based on the total college population, once can say with 95% confidence that the margin of sampling error is no greater than ± 4 percentage points." Explain what the statement means.

Verify this statement by finding the conservative margin of error for a 95% confidence interval for this sample. (Round your answer to three decimal places.)

Using the conservative margin of error found in part (a), give a 95% confidence interval for the percentage of all college student at this school who said the dining hall should be allow. (Round your answers to one decimal place.)

answer: hey there,

the answer you are looking for is a..

hope this you!

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.
