Answer:
And the 95% confidence interval would be given (0.419;0.481). And the best option would be:
b. .419 to .481
Step-by-step explanation:
We know the following info:
sample size selected
represent the number of people who favored Candidate AT
The sample proportion would be:
The confidence interval would be given by this formula
For the 95% confidence interval the value of and , with that value we can find the quantile required for the interval in the normal standard distribution.
And replacing into the confidence interval formula we got:
And the 95% confidence interval would be given (0.419;0.481). And the best option would be:
b. .419 to .481
Answer:
Step-by-step explanation:
sqrt(121) + sqrt(-75) - sqrt(81) - sqrt(-192) = 2 - 5.19615242i
<span>isolate the variable(x)
</span>(when you move numbers from one side to another you change the sign)
2x=22+73-11-23-67
2x=-6
divide both sides by 2
x=-3
Good evening
