Consider estimating a population proportion p. What is the most conservative sample size (erring on the large size) required in
just olya [345]

Answer:

The most conservative sample size is 2401.

Step-by-step explanation:

We are given the following in the question:

We are not given any approximation of s]ample proportion, thus,

\hat{p} = 0.5

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.5(1-0.5)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.5(1-0.5)}}{0.02}\\\\\sqrt{n}=49\\n = 2401

Thus, the most conservative sample size is 2401.

Help me pls
aksik [14]

Answer:

We know that Amber decided to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, and after this, the function representing the photo shares is:

f(x) = 3*(4)^x + 45

We do not know the initial function, but with the given information we can assume that the original equation is:

g(x) = 3*(4)^x

Then the new function is:

f(x) = g(x) + 45.

This is a vertical translation, remember that for a function h(x), a vertical translation of N units is written as:

k(x) = h(x) + N

if N is positive, we have a translation of N units up

if N is negative, we have a translation of N units down.

in this case we have;

f(x) = g(x) + 45

This means that f(x) is a vertical translation of 45 units of g(x), then:

the graph of the new function is 45 units above the original function.

When writing 3.7272727272... as a ratio of integers, what is the common ratio?
Law Incorporation [45]
The answer is:    "41 / 11 " ;  or, write as:  " 41 : 11 " .
__________________________________________________________
Explanation:
__________________________________________________________
72/99 = (72÷9) / (99÷9) = 8/ 11 . 

So, 3.727272727272...   =   "3 \frac{8}{11} " .

→  "3 \frac{8}{11} " =   [(11 *3) + 8] / 11 =  (33 + 8) / 11 = 41 / 11 .
__________________________________________________________
  "41 / 11" cannot be simplified any further; so the answer is:
__________________________________________________________
  "41 / 11 " ;  or, write as:  " 41 : 11 " .

Given V = 2πr2h, solve for h
Ipatiy [6.2K]
V=2*pi*r*2*h
V=(4*pi*r)*h
V/(4*pi*r)=h
so h=V/(4*pi*r)
