Days before a presidential election, a nationwide random sample of registered voters was taken. based on this random sample, it was reported that "52% of registered voters plan on voting for robert smith with a margin of error of plus or minus±3%." the margin of error was based on a 95% confidence level. can we say with 95% confidence that robert smith will win the election if he needs a simple majority of votes to win? choose the correct answer below.
a. no, because the margin of error can never be more than 1%.
b. yes, because 50% is within the bounds of the confidence interval.
c. yes, since over 50% of the voters in the sample say they will vote for robert smith.
d. no, because 50% is within the bounds of the confidence interval.

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.

c

step-by-step explanation: easy math

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
