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. The second sample had 20 observations, but the sample mean was smaller, and the sample variance was larger compared to the first sample. How do the widths of the two confidence intervals compare to each other?
