If the computed minimum sample size n needed for a particular margin of error is not a whole number, round the value of n (up or down) to the next (smaller or larger) whole number.
a) down; smaller
b) down; larger
c) up; larger
d) up; smaller

Answer:

The correct option is c.

Step-by-step explanation:

The margin of error is the range of values lower than and more than the sample statistic in a confidence interval. It is the number of percentage point by which the sample result will differ from the population result.

The general formula to margin of error is:

[tex]MOE=CV\times\frac{SD}{\sqrt{n}}[/tex]

Here,

CV = critical value

SD = standard deviation

n = sample size

Now, if the computed minimum sample size needed for a particular margin of error is not a whole number, then round the value of n up to the next larger whole number.

Thus, the correct option is c.
