Answer:
And the best option for this case would be:
A. 0.050 to 0.112.
Step-by-step explanation:
Data given
represent the real population proportion of who support the cnadite for the northern half state
represent the estimated proportion of who support the candidate for the northern half state
is the sample size required the northern half state
represent the real population proportion of who support the candidate for the southern half state
represent the estimated proportion of people who support the candidate for the southern half state
is the sample size for the northern half state
represent the critical value
The confidence interval for the difference of two proportions would be given by this formula
For the 95% confidence interval the value of and , with that value we can find the quantile in the normal standard distribution and we got.
Replacing into the formula we got:
And the best option for this case would be:
A. 0.050 to 0.112.
Answer:
x^6-1
Step-by-step explanation:
first you simplify the product it should look like this: (x^2)^3-1^3
then you simplify the expression by multiplying the exponents it should look like this: x^6-1^3
then you should raise any power equal 1 it should look like this: x^6-1 and thats your answer
Answer:
Y = 40
Step-by-step explanation:
Change 1/2 to 2/4
2/4 y + 6 = 3/4y - 4
subtract 2/4y
6 = 1/4y -4
add 4
10 = 1/4y
multiply by 4 to get fraction to 1y or y
y = 40
Answer:
Step-by-step explanation:
÷ 6
leave the fraction, change division to multiply, turn 6 upside down
= × ( cancel 2 and 6 by 2 )
= ×
=
=
