A simple random sample of pulse rates of 25 women from a normally distributed population results in a standard deviation of 10.9 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 0.05 significance level to test the claim that pulse rates of women have beats per minute. Complete parts (a) through (d) below. standard deviation equal to 10 ....

Find Test Statistic, P value, and Z score.

A simple random sample of pulse rates of 25 women from a normally distributed population results in a standard deviation of 10.9 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 0.05 significance level to test the claim that pulse 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 hypotheses. Choose the correct answer below.
O A. Ho: o # 10 beats per minute
B. Ho: o = 10 beats per minute
H1: 0 = 10 beats per minute
H1: 0+ 10 beats per minute
C. Ho: o2 10 beats per minute
D. Ho: o = 10 beats per minute
H1: 0< 10 beats per minute
H1: o< 10 beats per minute
b. Compute the test statistic.
