Question

Different standard deviations: Martin and Bianca are going to construct confidence intervals from different simple random samples. Both confidence intervals will have level 95% . Martin's sample has standard deviation =s21 , and Bianca's sample has standard deviation =s16 . Both sample sizes are the same. which confidence level is more likely to cover the mean

Step 1

A confidence interval is constructed using the sample mean, the standard deviation, and the critical value from the t-distribution (or z-distribution for large samples). The formula for a confidence interval is typically: \[ \text{Confidence Interval} = \bar{x} Show more…
