Express the confidence interval
marissa [1.9K]

Answer:

\hat p = \frac{0.244+0.326}{2}=0.285

ME = \frac{0.326-0.244}{2}=0.041

0.285 \pm 0.041

Step-by-step explanation:

For this case we have a confidence interval given as a percent:

24.4\% \leq p \leq 32.6\%

If we express this in terms of fraction we have this:

0.244 \leq p \leq 0.326

We know that the confidence interval for the true proportion is given by:

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

And thats equivalent to:

\hat p \pm ME

We can estimate the estimated proportion like this:

\hat p = \frac{0.244+0.326}{2}=0.285

And the margin of error can be estimaed using the fact that the confidence interval is symmetrical

ME = \frac{0.326-0.244}{2}=0.041

And then the confidence interval in the form desired is:

0.285 \pm 0.041

A water tanker can fill
VikaD [51]

Answer:

56 mins

Step-by-step explanation:

Number of gallons of water in the pool per minute;

750 divided by 35 = 150/7

Let the time needed to fill a 1,200 gallon pool be t.

t x 150/7 = 1,200

t x 21.42857142857143... = 1,200

t = 1,200/21.42857142857143

t = 56 mins

Nataliya [291]

Answer:

2.5 inches

Step-by-step explanation:

1 feet = 12 inches

The length is 16 ft x 12 = 192 inches

The length was scales by an unknown measure which i would represent with x . The equation is as follows

192 inches x a = 4 feet

a = 48

The kitchen was scaled by 48

10 x 12 = 120 inches

120/48 = 2.5 inches
