Answer: 126
Step-by-step explanation: i am so sorry if i am wrong
Answer:
D. No, because 50% is within the bounds of the confidence interval.
Step-by-step explanation:
"52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus±3%"
This means that the 95% confidence interval for the percentage of people that plan on voting for Robert Smith is
(52-3 = 49%, 52+3 = 55%).
We can't say that he will win the election, because at the 95% confidence level, the proportion is not guaranteed to be above 50%.
So the correct answer is:
D. No, because 50% is within the bounds of the confidence interval.
A)64 it 2*4*8=64 it is multiplied
Answer:

So then the best option would be:
a. 1/25
Step-by-step explanation:
For this case we assume that the sample space for the numbers is :
![S_1= [A,B,C,D,E]](https://tex.z-dn.net/?f=%20S_1%3D%20%5BA%2CB%2CC%2CD%2CE%5D)
And the sample space for the numbers is:
![S_2 =[1,2,3,4,5]](https://tex.z-dn.net/?f=%20S_2%20%3D%5B1%2C2%2C3%2C4%2C5%5D)
Both sampling spaces with a size of 5.
We define the following events:
A="We select a 2 from the numbers"
B= "We select a E from the letters"
We can find the individual probabilities for each event like this:


And assuming independence we can find the probability required like this:

The last probability is the probability of obtain obtain a 2 AND an E
So then the best option would be:
a. 1/25
