Answer:
The mean and standard deviation of the number preferring the incumbent is mean = 330, standard deviation = 10.59.
Step-by-step explanation:
We are given that From previous polls, it is believed that 66% of likely voters prefer the incumbent.
A new poll of 500 likely voters will be conducted. In the new poll the proportion favoring the incumbent has not changed.
Let p = probability of voters preferring the incumbent = 66%
n = number of voters polled = 500
<u>So, the mean of the number preferring the incumbent is given by;</u>
Mean =
=
= 330 voters
<u>And, standard deviation of the number preferring the incumbent is given by;</u>
Variance =
=
= 112.2
So, Standard deviation =
=
= 10.59
Answer:
32 cm
Step-by-step explanation:
As we could see if the image was a full rectangle with width is 7 cm and the length is 9 cm, the perimeter of it would be 32 cm.
Sn=So(1+p/100*2)
2000*(1+3/100*2)=2000(1+3/50)=2000*53/50=40*53=2120$
My answer:2120$
Divide then multiply by 100:
280 / 3500 = 0.08
0.08 x 100 = 8%
Answer: 8%
