Chapter 5 (8 points) The effect of observer training on measurement of blood pressure: A goal was that the difference in recorded blood pressure between the observer and trainer be 52 mmHg in absolute value. It was reported that the mean difference in systolic blood pressure (SBP) between observers and trainers (i.e., mean observer SBP min trainer SBP) = mean (D) was 0.2 mmHg with Sg=2.4 mmHg. If we assume that the distribution of D is normally distributed, then what % of (observer, trainer) pairs have a mean difference of ≥2 mmHg in absolute value (i.e., either ≥2 mmH or ≤−2 mmHg) ?
