Answer:
b. We are 95% confident that the interval (122, 138) contains the population mean systolic blood pressure of all employees.
g. We are 95% confident that the population mean systolic blood pressure of all employees is in the interval (122, 138).
Step-by-step explanation:
The confidence interval from the question does not align with the confidence interval from the answer choices.
A confidence interval represents a set of values within which we estimate, with a specified level of confidence, that a certain population parameter lies.
In this case, with a range of (122, 138), we are 95% sure that the true population mean systolic blood pressure fits between those two numbers.
This interval is calculated based on data from a sample, but it reflects something regarding the parameter of the population.
It does not indicate probabilities for specific values or sample statistics.
Thus, based on this understanding, the valid statements are:
b. We are 95% confident that the interval (122, 138) contains the population mean systolic blood pressure of all employees.
g. We are 95% confident that the population mean systolic blood pressure of all employees is in the interval (122, 138).
