Question
**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 \( [ \_\_\_\_ \text { input box} ] \)
