If the sample size is increased and the standard deviation and confidence level stay the same, then the margin of error will also be increased.

- True
- False

Step 1

**Margin of error:**

The margin of error helps in constructing confidence intervals, which gives a range of plausible values for the population parameter. Margin of error is nothing but a range of values above and below the value of sample statistic.

For example, the formula of margin of error for sample mean of *z*-test is given below.

Step 2

**Properties of Margin of error:**

Some of the properties of margin of error is as follows:

- The margin of error value gets smaller as
*n*(sample size) tends to infinity. - Higher the value of level of significance, higher the margin of error.
- Higher the standard...
