You wish to estimate a population proportion with a confidence interval with a margin of error no larger than 0.03. You have a b
NikAS [45]

Answer:

The answer is 0.8788

Step-by-step explanation:

<em>From question given, let us recall the following:</em>

<em>We know that  Ƶα /2  * √p (1-p)/n</em>

<em>when we use  n≤  5000/10 =500</em>

<em> P = 0.75</em>

<em>The Margin of error = 0.03</em>

<em>Putting this values together we arrive at </em>

<em> Ƶα/2 = 0.03/√0.75 * 0.25/500 </em>

<em>= 1.549</em>

<em>Now,</em>

<em>Ф (1.549) = 0.9394</em>

<em>Therefore the confidence level becomes:</em>

<em> 1- (1-∝)/2 = 0.9394</em>

<em>∝ = 0.8788</em>

<em>The answer is 0.8788</em>

Please i want to know how to find slope intercepts
algol [13]

Answer:

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Step-by-step explanation:

The general formula is y = mx +b.

m = slope.

b = y-intercept of the line

Which function f (x) , graphed below, or g (x) , whose equation is g (x) = 3 cos 1/4 (x + x/3) + 2, has the largest maximum and
Leya [2.2K]

Answer:

g(x), and the maximum is 5

Step-by-step explanation:

for given function f(x), the maximum can be seen from the shown graph i.e. 2

But for the function g(x), maximum needs to be calculated.

Given function :

g (x) = 3 cos 1/4 (x + x/3) + 2

let x=0 (as cosine is a periodic function and has maximum value of 1 at 0 angle)

g(x)= 3 cos1/4(0 + 0) +2

    = 3cos0 +2

     = 3(1) +2

     = 3 +2

     = 5 !
