What is the mean value of the six BP readings 115, 120, 123, 121, 121, 112 rounded to the nearest whole number?

Explanation:
The mean value is the average of all readings, so add them up and divide by how many there are. 115 + 120 + 123 + 121 + 121 + 112 = 712. Then 712 divided by 6 equals 118.666..., which rounds to 119 to the nearest whole number. The decimal part is 0.666..., which is greater than 0.5, so it rounds up. This gives the overall average BP across the six measurements.
