![**Estimating Sample Size for Pulse Rates of Adult Males**
In a study, the pulse rates of 153 randomly selected adult males vary from a low of 35 beats per minute (bpm) to a high of 99 bpm. We aim to determine the minimum sample size required to estimate the mean pulse rate of adult males within a 95% confidence interval, ensuring the sample mean is within 3 bpm of the population mean. Follow the steps below to complete this analysis.
1. **Find the sample size using the range rule of thumb to estimate σ (standard deviation):**
\[
\text{n} = \_\_\_\_
\]
*(Round up to the nearest whole number as needed.)*
2. **Assume that σ = 12.3 bpm, based on the value σ = 12.3 bpm from the sample of 153 male pulse rates:**
\[
\text{n} = \_\_\_\_
\]
*(Round up to the nearest whole number as needed.)*
3. **Compare the results from parts (a) and (b). Which result is likely to be better?**
- The result from part (a) is \( [ \_\_\_\_ \text { dropdown menu option} ] \)
- The result from part (b) is \( [ \_\_\_\_ \text { dropdown menu option} ] \)
- The result from \( [ \_\_\_\_ \text { dropdown menu option} ] \) is likely to be better because \( [ \_\_\_\_ \text { input box} ] \)
**Instructions:**
- Enter your answers in each of the answer boxes.
