Express the confidence interval 0.333 less than p less than 0.555 in the form Modifying Above p with caret plus or minus Upper E
olga_2 [115]

Answer: = 0.444\pm 0.111

Step-by-step explanation:

The confidence interval for population proportion(p) is given by :-

\hat{p}-E  (1)

It is also written as : \hat{p}\pm E         (*)

The given confidence interval for population proportion :

0.333 (2)

Comparing (1) and (2) , we get

Lower limit = \hat{p}-E=0.333 (3)

Upper limit = \hat{p}+E=0.555  (4)

Adding (3) and (4) , we get

2\hat{p}=0.888\\\Rightarrow\ \hat{p}=\dfrac{0.888}{2}=0.444

Put value of \hat{p}=0.444 in (2) , we get

0.444+E=0.555\\\\\Rightarrow\ E=0.555-0.444=0.111

Put values of \hat{p}=0.444  and E= 0.111 in (*) , we get

Required form = 0.444\pm 0.111

Simplify square root of 72
LuckyWell [14K]
(square root of  72)  =  square root of (36  times  2)

That's the same as  (square root of  36)  times  (square root of  2).

But the square root of  36  is  6 .

So the square root of  72  is    (6)  times  (square root of  2) .
