The article “Automatic Filtering of Outliers in RR Intervals Before Analysis of Heart Rate Variability in Holter Recordings: a Comparison with Carefully Edited Data” (M. Karlsson, et al., Biomedical Engi- neering Online, 2012) reports measurements of the total power, on the log scale, of the heart rate variabil- ity, in the frequency range \(0.003 \text { to } 0.4 \mathrm{~Hz}\), for a group of 40 patients aged 25–49 years and for a group of 43 patients aged 50–75 years. The mean for the patients aged 25–49 years was 3.64 with a standard deviation of 0.23, and the mean for the patients aged 50–75 years was 3.40 with a standard deviation of 0.28. Find a
\(95 \%\) confidence interval for the difference in mean power between the two age groups.
