R.I.P YOUR PHONE!! I'm "learning" this in my online school- Haven't been paying attention at all to anything - SoRrY cHiLdD!
Sorry but where is the picture? I’m confused..
Answer: 0.031 .
Step-by-step explanation:
The standard error of the sample proportion is given by :-
![SE_p=\sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=SE_p%3D%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
, where p= Sample proportion and n is the sample size.
As per given , we have
In an opinion poll, 25% of a random sample of 200 people said that they were strongly opposed to having a state lottery.
i.e. p= 0.25 and n= 200
Then , the standard error of the sample proportion ![=\sqrt{\dfrac{0.25(1-0.25)}{200}}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cdfrac%7B0.25%281-0.25%29%7D%7B200%7D%7D)
![=\sqrt{\dfrac{0.25\times0.75}{200}}=\sqrt{0.0009375}\\\\=0.0306186217848\approx0.031](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cdfrac%7B0.25%5Ctimes0.75%7D%7B200%7D%7D%3D%5Csqrt%7B0.0009375%7D%5C%5C%5C%5C%3D0.0306186217848%5Capprox0.031)
Hence, the standard error of the sample proportion is approximately <u>0.031 </u>.
Answer:
It should be a better deal.
Step-by-step explanation:
In the question a bank that gives him 6.8% it says it will pay for the computer in a year. So if another bank says that they with offer 6.9% then he will probably have enough for the computer.
I do not know if this is right or not it is just my opinion!
100 x 5= 500 ($)
50 x 5= 250 ($)
40 x 5=200($)
so, she needs to sell min. 40 and mac. 100 cakes to reach her goal.
correct answer is b. 40_< x >_100
