The pulse rates of 153 randoml

Uncategorized
The pulse rates of 153 randomly selected adult males vary from a low of 41 bpm to a high of 121 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 99​% 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 (i recently asked this and the answer ‘127′ was incorrect. in the work the person showed, it appeared they did 90% rather than 99%)

b. Assume that σ = 11.3 bpm, based on the value of s = 11.3 bpm for the sample of 153 male pulse rates.

c. Compare the results from parts (a) and (b). Which result is likely to be better?
