For a simple random sample of pulse rates of women (measured in beats per minute),n=144ands=13.9.The normal range of pulse rates of adults is typically given as60to100beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of10beats per minute. Use the sample results with a0.01significance level to test the claim that pulse rates of women have a standard deviation equal to10beats per minute; see the accompanying JMP display that results from using the original list of pulse rates instead of the summary statistics. (Hint: The bottom three rows of the display provide P-values for a two-tailed test, a left-tailed test, and a right-tailed test,respectively.)What do the results indicate about the effectiveness of using the range rule of thumb with the "normal range" from60to100beats per minute for estimatingσin this case?Assumethat the simple random sample is selected from a normally distributed population.LOADING...Click the icon to view the JMP display.
