The manager of the Quick Stop Corner Convenience Store (which never closes) sells four cases of Stein beer each day.

Suppose we’re running a study to see if Americans’ blood pressure has risen in the last couple of decades.  In adults in 2003, the best estimate for the population’s average systolic blood pressure was 128 mmHg. In our study with n = 57 n = 57 patients, we found a sample mean systolic blood pressure of 137 mmHg. The null hypothesis for our study should be μ = ? \mu = ? .  Enter your answer only as a number (don’t type the “mmHg” part).
