Twо different rаndоm sаmples were cоllected from the sаme population. Each sample has a different sample size. Confidence intervals (two-sided) were constructed on the population mean, one for each sample. The first sample had 60 observations, had a sample mean of 18.2, and a sample standard deviation of 3.5. A 90% confidence interval was constructed. The second sample had 35 observations, had a sample mean of 25.9, and a sample standard deviation of 4.9. A 95% confidence interval was constructed. How do the widths of the two confidence intervals compare to each other?
