Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals

Alekssandra [29.7K]

Answer:

(0.767,0.833)

Step-by-step explanation:

The 95% confidence interval for population proportion p can be computed as

$p-z_{\frac{\alpha }{2} } \sqrt{\frac{pq}{n} }$

The z-value associated with 95% confidence level is 1.96.

whereas p=x/n

We are given that x=440 and n=550.

p=440/550=0.8

$0.8-1.96\sqrt{\frac{0.8(0.2)}{550} }$

$0.8-1.96\sqrt{\frac{0.16}{550} }$

$0.8-1.96\sqrt{0.00029 }$

$0.8-1.96(0.01706)$

$0.8-0.03343$

$0.76657$

Thus, the required confidence interval is

0.767<P<0.833 (rounded to 3 decimal places)

Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)

PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma

GenaCL600 [577]

Answer:

$x=-6,\\y=6$

Step-by-step explanation:

Rewrite the system of equations as:

$\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}$

Subtract the second equation from the first to isolate $x$ :

$-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}$

Plug in $x=-6$ into any of the equations above and solve for $y$ :

$-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}$

Verify that the solution pair $(-6, 6)$ works $\checkmark$

Therefore, the solution to this system of equations is:

$x=-6,\\y=6$
