Refer to Data Set 1 in Appendix B and find the maximum and minimum pulse rates for males, then use those values with the range rule of thumb to estimates. How many adult males must you randomly select and test if you want to be 95% confident that the sample mean pulse rate is within 2 beats (per minute) of the true population mean m. The standard deviation of the 40 pulse rates of males in Data Set 1 is 10.3 beats per minute. If, instead of using the range rule of thumb, the standard deviation of the sample is used as an estimate of s, is the required sample size very different? Which result is likely to be closer to the correct sample size?

Find the confidence interval using the known value of S. What is different about the normality requirement for a confidence interval estimate of s and the normality requirement for a confidence interval estimate of µ? Data Set 1 in Appendix B includes 40 pulse rates of men, and those pulse rates have a mean of 67.3 beats per minute and a standard deviation of 10.3 beats per minute. That data set also includes 40 pulse rates of women, and ...The author had difficulty finding the percentage of people who write with their left hand.
