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

yulyashka [42]

Answer:

$m=4$ or $m=\frac{4}{1}$

Step-by-step explanation:

To find slope we use the slope formula
