Question

Kindly, explain properly.

The mean of a set of length measurements for object A is 1.25 ± 0.05 m, and the mean of similar measurements for the length of object B is 1.32 ± 0.20 m. Can we conclude that B is longer than A? Explain your reasoning.

Answer 1

Explanation:

You cannot conclude this

A can be as short as 1.20 and as long as 1.30

B can be 1.12 to 1.52 m

so B COULD be shorter than A !
