A new fertilizer was applied to the soil of 146 bean plants. 23% showed increased growth. Find the margin of error and 95% confi
USPshnik [31]

Answer:

The significance level for this case would be \alpha=1-0.95=0.05 and the critical value for this case would be:

z_{\alpha/2}=1.96

The margin of error is given by:

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

And replacing we got:

ME = 1.96 \sqrt{\frac{0.23*(1-0.23)}{146}} =0.0683

And the margin of error for this case would be ME = 0.07

Step-by-step explanation:

For this case we have the following dataset given:

n= 146 represent the sample size

\hat p =0.23 represent the estimated proportion of interest

Conf=0.95 represent the confidence level

The significance level for this case would be \alpha=1-0.95=0.05 and the critical value for this case would be:

z_{\alpha/2}=1.96

The margin of error is given by:

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

And replacing we got:

ME = 1.96 \sqrt{\frac{0.23*(1-0.23)}{146}} =0.0683

And the margin of error for this case would be ME = 0.07

Express your answer as a polynomial in standard form.
Musya8 [376]

Answer:

f(g(x)) = 6x^2+6x+11

Step-by-step explanation:

f(g(x)) = 2(3x^2+3x+7) - 3\\f(g(x)) = 6x^2 + 6x + 14 - 3\\f(g(x)) = 6x^2+6x+11
