For a simple random sample of pulse rates ofwomen (measured in beats per minute), n=143 and s=13.0.The normal range of pulse rates of adults is typically given as 60to 100 beats per minute. If the range rule of thumb is applied tothat normal range, the result is a standard deviation of 10beats per minute. Use the sample results with a 0.10 significancelevel to test the claim that pulse rates of women have a standarddeviation equal to 10 beats per minute; see the accompanyingJMP display that results from using the original list of pulserates instead of the summary statistics. (Hint: The bottomthree rows of the display provide P-values fora two-tailed test, a left-tailed test, anda right-tailed test, respectively.) What do the resultsindicate about the effectiveness of using the range rule of thumbwith the "normal range" from 60 to 100\ beats per minute forestimating σ in this case? Assume that the simple randomsample is selected from a normally distributed population.
a. Let σ denote population standard deviation of the pulse ratesof women (in beats per minute). Identify the null andalternative hypotheses.
b. Test Statistic?
c. P-Value?
d. Test Statistic of the P-value?
