Z score requires historical data. Assuming everyone was equally spread between 60-100 bpm, the average is 80. Sample size is 41 (1 for each value between 60-100, inclusive). Mean is 80, Standard Deviation is 11.98. So then (69 - 80) / 11.98, Z = -0.918. This answer is insignificant though, because you need data to calculate a Z score. Heart rate can be grouped by age, weight, habits, etc.
