Answer:
Width of confidence interval will increase.
Step-by-step explanation:
The sample size as an effect on the width of the confidence interval being calculated as it determines the value of the error margin. In general, increasing the sample size reduces the width of the confidence that interval while decrease in its value increases the error margin and hence the confidence interval.
Confidence interval :
Xbar ± Error margin
Error margin = Tcrit * s/ sqrt(n)
n = sample size
Being the denominator, a decrease in its value will result in an increase in error margin.
