Step-by-step explanation:
The weighted mean is used to calculate the mean of numbers which don't have the same "weight" or statistical relevance. In this case, that relevance is based on the sample size of each group from which the mean reaction times were obtained.
For all three samples, the weighted mean is obtaining by multiplying each one of the mean reaction times by its n value, adding them, and dividing that result by the sum of all n values.
