Mathematics
Your company markets a computerized device for detecting high blood pressure once per hour at a randomly selected time throughout a 12-hour period. Then it calculates the mean systolic (top number) pressure for the sample of measurements. Based on the sample results, the device determines whether there is convincing evidence that the individual's actual mean systolic pressure is greater than 130. If so, it recommends that the person seek medical attention. State appropriate null and alternative hypotheses in this setting. Be sure to define your parameter.
