Question

A simple random sample of 60 women  from a normally distributed population results in a standard deviation of 12.7 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range , the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. Complete parts a through d below . 
b. Compute the test statistic x^2 ___ ( round to three decimal places as needed ) 

c. Find the p-value ___ ( round to four decimal places as needed ) .

d. State the conclusion 

If the p value is less than or equal to the level of significance there is sufficient evidence to reject the null hypothesis. Otherwise there is insufficient evidence to reject the null hypothesis. 

a. Identify the null and alternative hypotheses. Choose the correct answer below.
O A. H, o= 10 beats per minute
H,:o#10 beats per minute
O B. H, o= 10 beats per minute
H o< 10 beats per minute
O C. H, o2 10 beats per minute
H o<10 beats per minute
O D. H, o10 beats per minute
H o= 10 beats per minute
