The pulse rates of 155 randomly selected adult males vary from a low of 41 bpm to a high of 109 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 2 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 n= type a whole (type a whole number.)
b. assume that σ = 11.6 bpm, based on the value s = 11.6 bpm from the sample of 155 male pulse rates. n= (type a whole number.)
c. compare the results from parts (a) and (b). which result is likely to be better?
the result from part ( result from part (b). the result likely
larger than
smaller than
