To study the effect of soothing music on a person’s blood pressure, two random samples of 220 adults were taken. One sample (sample 1) listened to soothing music for 5 min prior to having their blood pressure taken, while the other sample (sample 2) sat in silence. From previous studies, it was found that both populations have a standard deviation of 39.18. The average systolic blood pressure from the music sample was 114.5. The average systolic blood pressure from the silent sample was 122.8. Construct a 98% confidence interval on the difference in population mean blood pressures (music – silent).
