If other factors are held constant, what happens to a confidence interval if the sample variance increases? The range of t score

Firlakuza [10]

Answer:

The standard error increases and the width of the interval increases

Step-by-step explanation:

The variance is equal to the square of the standard deviation. An increase in variance will increase the standard deviation.

The width of the confidence interval can be defined as:

$W=UL-LL=2z\sigma/\sqrt{n}$

The width is proportional to the standard deviation, so when the variance increases, the standard deviation and also the width of the interval increases.
