**Problem Statement:**
The pulse rates of 174 randomly selected adult males vary from a low of 41 bpm to a high of 117 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 90% confidence that the sample mean is within 3 bpm of the population mean. Complete parts (a) through (c) below.
**a.** Find the sample size using the range rule of thumb to estimate σ (standard deviation).
**Calculated Sample Size:**
n = 109 (Round up to the nearest whole number as needed.)
**b.** Assume that σ = 11.6 bpm, based on the value s = 11.6 bpm from the sample of 174 male pulse rates.
n = [ ] (Round up to the nearest whole number as needed.)
