The pulse rate of 169 randomly selected adult males vary from a low of 36 bpm to a high of 96 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

A. Find the sample size using the range rule of thumb to estimate o

N=____

B. Assume that o=10.6 bpm based on the vaule s= 10.6 bpm from the sample of 169 Male pulse rates

N=______

C. Compare the results from part a and b

The result from part a is larger/smaller/same

as the result from part b the result from part b is likely to be better because it is smaller/larger/uses a better same estimate of o
