a. 95% of the sample of employees have a systolic blood pressure between 122 and 138.

b. 95% of the population of employees have a systolic blood pressure between 122 and 138.

c. If the procedure were repeated many times, 95% of the resulting confidence intervals would contain the population mean systolic blood pressure.

d. If the procedure were repeated many times, 95% of the time the population mean systolic blood pressure would be between 122 and 138.

e. If the procedure were repeated many times, 95% of the time the sample mean systolic blood pressure would be between 122 and 138.
