4(3/2y+2)+3y=26
6y+8+3y=26
add the y's together
9y+8=26
subtract 8 on both sides
9y=18
divide by 9 on both sides
y=2
(then substitute 2 for y)
4x+3(2)=26
4x+6=26
subtract 6 on both sides
4x=20
divide by 4 on both sides
x=5

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Level of Significance, $\alpha = 0.05$

Sample Size, $n = 120$

Sample Proportion, $\hat{P} = 0.600$

$z -value = Z_{\frac{\alpha}{2}} = 1.960 \ \ [excel formula =NORMSINV(\frac{\alpha}{2})]$

Standard Error $SE = \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = 0.0447$

margin of error $E = Z\times SE = 1.960 \times 0.0447 = 0.0877$

When $95\%$ Confidence Interval

Interval Lower Limit $= \hat{p} - E = 0.600 - 0.0877 = 0.5123$

Interval Upper Limit $=\hat{p}+ E = 0.600 + 0.0877 = 0.6877$
