The formula is y=mx+b, m being the slope and b being the y intercept.

So if you simplify your equation, it's 5x+6=y

Slope is 5, y intercept is 6

Answer:

n=438

Step-by-step explanation:

-Given the sample proportion $\hat p=0.24$ and the confidence level is 95%.

-The sample size can be calculated using the formula;

$ME=z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}$

#Substitute parameters in the formula and make n the subject of the formula;

$ME=z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\=z_{0.025}\sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\n=(\frac{z_{0.025}}{ME})^2\hat p(1-\hat p)\\\\\\=(\frac{1.96}{0.04})^2\times 0.24\times 0.76\\\\=437.94\approx 438$

Hence, the desired sample size is n=438
