​(Round to one decimal place as​ needed.)

To construct a 95% confidence interval for the mean pulse rates of adult females and males, we need the following information from the data set: the sample mean (\( \bar{x} \)), the sample standard deviation (\( s \)), and the sample size (\( n \)) for both groups.

The formula for the confidence interval is:

\[
\bar{x} \pm t \left( \frac{s}{\sqrt{n}} \right)
\]

where \( t \) is the t-score corresponding to the desired confidence level and degrees of freedom (\( n-1 \)).

### Steps to Construct the Confidence Interval:

1. **Calculate the sample mean (\( \bar{x} \))** for both groups.
2. **Calculate the sample standard deviation (\( s \))** for both groups.
3. **Determine the sample size (\( n \))** for both groups.
4. **Find the appropriate t-score** for 95% confidence based on the degrees of freedom.
5. **Use the formula** to calculate the confidence intervals.
