A political party wishes to estimate the proportion of voters that support the party in a particular state. The party will poll a random sample of n voters from the state. Which of the following is likely to result in the largest margin of error? a. n = 500, confidence level 95%
b. n = 500, confidence level = 99%
c. n = 500, confidence level = 90%
d. n= 300, confidence level 95%
e. n = 300, confidence level = 90%

Option D

Step-by-step explanation:

Generally the equation for Margin of Error is mathematically given by

Condition for Largest M.E

n has to be smallest and Z value has to be largest.

Where

From options

Smallest

Largest Z value respects to

Therefore

n= 300, confidence level 95%

Option D

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
