Identify the null hypothesis and alternative hypothesis

Reference no: EM131167981

In a pulse rate research, a simple random sample of 81 men results in a mean of 75 beats per minute, and a standard deviation of 12 beats per minute. Based on the sample results, the researcher concludes that the pulse rates of men have a standard deviation greater than 10 beats per minutes. Use a 0.05 significance level to test the researcher's claim.
