5. It is known that the mean systolic blood pressure for Canadian males aged 35 to 44 years is 128, with a standard deviation of 15. The Delta Widget-flanging Company tests 72 employees in this age group and finds they have a mean systolic blood pressure of 126.07. a) Could we conclude the DWC's male employees in this age group have a lower systolic blood pressure than in the general population? b) How large a sample would be required to give a 95% confidence interval for employees systolic blood pressure with a margin of error of 2?
