The pulse rates of 178 randomly  selected adults males vary from  a low 36 bpm to a high of 112. Find  the minimum  sample size required  to estimate  the mean pulse rate of adult males. Assume that we want 95 % 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  b) assume that  standard  deviation  = 12.4 bpm, bases on the value s= 12.4 bpm from the sample of 178 male pulse rates.  n= c) compare the results from parts a) and b) which  result is likely to be  better?
