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

Please help! i can’t write the equation on here so look at the picture.

Anvisha [2.4K]

Answer:

So if x= 1 , y= -20 , z = -5 , we just have to replace those values on the equation

$\frac{\sqrt{yz}}{(z-x)^{2} + y } =$ $\frac{\sqrt{(-20) * (-5)}}{(-5-1)^{2} + (-20) } =$ $\frac{\sqrt{100}}{(-6)^{2} -20 }$ $= \frac{10}{16} =\frac{5}{8}$
