Answer: The standard error of the mean = 0.5

Step-by-step explanation:

Given : Sample size : n = 144

Standard deviation : $\sigma=6\text{ hours}$

The formula to find the standard error of the mean is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$

i.e. $S.E.=\dfrac{6}{\sqrt{144}}=0.5$

Hence, the standard error of the mean =0.5
