Answer:

2 $\sqrt{6}$

Step-by-step explanation:

Area of a square = $s^{2}$ (s is a side length)

24 = $s^{2}$

$\sqrt{24}$ = $\sqrt{s^{2} }$

$\sqrt{24}$ = s

$\sqrt{(4)(6) }$ = s

avanturin [10]

Answer:

We are 95% confident that the true proportion of TV audience is between 65.15% and 65.85%

Step-by-step explanation:

-From the given information, $\hat p=0.65$ .

-We calculate the confidence interval using this value at 95% confidence level:

$CI=\hat p\pm z \sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\\\=0.65\pm 1.96\times \sqrt{\frac{0.65\times 0.35}{12000}}\\\\\\=0.65\pm 0.0085\\\\\\=[0.6415,0.6585]$

So, the 95% confidence interval is (0.6515,0.6585).

Hence, we are 95% confident that the true proportion of TV audience is between 65.15% and 65.85%.
