Asimple random sample of 38 men from a normally distributed population results in a standard deviation of 12.9 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. a Identify the nuland alternative hypotheses. Choose the correct answer below. OB. H:0= 10 beats per minute H:o<10 beats per minute OA H: 0= 10 beats per minute H: 0# 10 beats per minute OC. H: G 10 beats per minute OD. H: 02 10 beats per minute H:G<10 beats per minute H:0= 10 beats per minute b. Compute the test statistic. (Round to three decimal places as needed.) c. Find the P-value. Pvalue=O Round to four decimal places as needed.)

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.
a Identify the nuland alternative hypotheses. Choose the correct answer below.
OB. H:0= 10 beats per minute
H:o<10 beats per minute
OA H: 0= 10 beats per minute
H: 0# 10 beats per minute
OC. H: G 10 beats per minute
OD. H: 02 10 beats per minute
H:G<10 beats per minute
H:0= 10 beats per minute
b. Compute the test statistic.
(Round to three decimal places as needed.)
c. Find the P-value.
Pvalue=O
