Babies weighing less than 2500 grams are considered to be of low birth weight. Can you conclude that the average birth weight is greater than 2500 grams? O No, the entire confidence interval is below 2500. O Yes, the entire confidence is above 2500. O No conclusions can be drawn since the confidence interval contains 2500.

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 7 adults. The following table presents the results. Systolic 116 107 105 113 118 133 110 Diastolic 70 71 66 77 88 91 74 Construct a 99% confidence interval for the slope. Round the answers to at least four decimal places.
