Question
KE The heart rate variability (HRV) of police officers was the subject of research published in a biology journal. HRV is defined as the variation in the time intervals between heartbeats. A measure of HRV was obtained for each in a sample of 352 police officers from the same city (The lower the measure of HRV, the more susceptble the officer is to cardiovascular disease) For the 75 officers diagnosed with hypertension, a 95% confidence interval for the mean HRV was (6.9,126.6). For the 277 officers that are not hypertensive, a 95% confidence interval for the mean HRV was (142 8,186.7) Use this information to complete parts a through d below GEED a. What confidence coefficient was used to generate the confidence intervals? 95 (Type an integer or a decimal. Do not round) b. Give a practical interpretation of both of the 95% confidence intervals. Use the phrase "95% confident in your answer The researchers can be 95% confident that the true mean HRV for all hypertensive police officers in the city is between and A smlar statement can be made about the police officers without hypertension. (Type integers or decimals. Do not round) sample world
