The sampling distribution of the sample means for the random sample of 100 dogs will be 0.25.
<h3>How to compute the sample mean?</h3>
From the given information, the population distribution of the QDA scores for the fur of dogs is roughly uniform with mean 5.4 and standard deviation is 2.5.
In this case, the sampling distribution of the sample means will be:

= ✓0.0625
= 0.25
In conclusion, the correct option is 0.25.
