Please kindly check explainations for the answers

Step-by-step explanation:

a) 95% confidence coefficient was used

b) If repeated samples were taken and the 95%confidence interval was computed for each sample,95% of the intervals would contain the population mean

The researchers can be 95% confident that the true mean HRV for all hypertensive police officers in the city is between _9.4_ and 129.1__. A similar statement can be made about the police officers without hypertension.
