Answer:

1.38

Step-by-step explanation:

The point estimate for the population standard deviation of the length of the walking canes is given as the squareroot of variance. Since variance is provided as 1.9 then the standard deviation will be

[tex]\sqrt 1.9=1.37840487520902\approx 1.38[/tex]

Therefore, rounded off to two decimal places, the standard deviation is approximately 1.38
