A simple random sample of pulse rates of 50 women from a normally distributed population results in a standard deviation of 12.3 beats per minute. The normal range of pulse rates of adults is typically given a 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 th rates of women have a standard deviation equal to 10 beats per minute. Complete parts (a) through (d) below. a. Identify the null and alternative hypbtheses. Choose the correct answer below, O B. Ho: o= 10 beats per minute O A. Ho: o* 10 beats per minute H:0 = 10 beats per minute H:o<10 beats per minute O C. Ho: o2 10 beats per minute O D. Ho: o = 10 beats per minute H,:o<10 beats per minute H:o+ 10 beats per minute b. Compute the test statistic. (Round to three decimal places as needed.)
