7) The National Center for Health Statistics reports that the mean systolic blood pressure for all females aged 40 to 50 years is 125. A researcher randomly samples 25 female executives aged 40 to 50 years and determines their sample mean systolic blood pressure to be 129 with a sample standard deviation of 9. Using this sample result, perform the 5 step hypothesis test to determine if the researcher can conclude that all female executives aged 40 to 50 years have a higher mean systolic blood pressure at a = 5%? I. State the hypotheses (in words & symbols): Ho: Ha: II. Determine the model to test Ho a) Can you use a normal distribution for the Hypothesis Testing model to perform this test? Please explain your answer. If not, then what distribution could you use as the Hypothesis Testing model b) Using the appropriate notation, state the MEAN & STD ERROR of the sampling distribution: Mean: (to 2 decimal places) STD Error: (to 2 decimal places)
