Bruce's three measurements are 19cm, 20cm, 23cm. calculate the average value of his measurements
Answer: We are given:
Bruce has three measurements measuring 19cm, 20cm, 23cm.
We need to find the average value of Bruce's measurements.
We know the formula of average is:
[tex]\bar{x}=\frac{\sum x}{n}[/tex]
Where:
[tex]\sum x[/tex] is the sum of observations
[tex]n[/tex] is the number of observations
[tex]\therefore[/tex] average value of Bruce's measurements is:
[tex]\bar{x}=\frac{19+20+23}{3}[/tex]
[tex]=\frac{62}{3} =20.67 \approx 21[/tex]
Hence the average value of Bruce's measurements is 21cm
