Suppose a recent business article reported that 52 % of small business owners in the United States preferred a Simplified Employee Pensions Individual Retirement Account (SEP IRA) to a Roth IRA. The local chamber of commerce wanted to see if the proportion of small business owners who prefer the SEP IRA was less in their community. They randomly sampled 100 small business owners and asked which of the two retirement accounts they preferred. The survey found that 39 small business owners preferred the SEP IRA. A one-sample ‑test will be used to determine if the local community proportion is less than the proportion in the United States. The null hypothesis is 0:=52 where = the proportion of all small business owners in this community who prefer the SEP IRA.

the square root of what number? if you add that, then someone will probably answer the question.

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake

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.

this is a good question! i'll do some research and come back when i have the answer!
