Advertisement The pooled variance is a better estimate of the (unknown) common group variance than either of the individual group variances. If each group has the same number of observations, then the pooled variance is a simple average. How do you use pooled standard deviation? To compute the pooled SDRead More →

SOLVED:An atomic absorption method for determination of copper in fuel samples yielded a pooled standard deviation of spooled =0.27 μg Cu / mL(s →σ). The analysis of an oil from a reciprocating aircraft engine showed a copper content of 7.91 μg Cu / mL. Calculate the 95 and 99 % confidence intervals for the result if it was based on (a) a single analysis, (b) the mean of 4 analyses, and (c) the mean of 16 analyses.
