Find:Test statisticP-value Conclusion A simple random sample of 46 men from a normally distributed population results in a standard deviation of 12.7 beats per minute. The normal range of pulse rates ofadults 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 perminute. Use the sample results with a 0.05 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. Completeparts (a) through (d) below.a.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Find: Test statistic P-value Conclusion

A simple random sample of 46 men 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 0.05 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 null and alternative hypotheses. Choose the correct answer below.
O A. Ho: o = 10 beats per minute
B. Ho: 0 = 10 beats per minute
H1: 0< 10 beats per minute
