Twо different rаndоm sаmples were cоllected from the sаme population. Each sample has a different sample size. 95% confidence intervals (two-sided) were constructed on the population mean, one for each sample. The first sample had 30 observations.

How do the widths of the two confidence intervals compare to each other?
