Answer:
To find the mean of means, we need to add up the means of all five years and then divide by 5 (the number of years).
Mean of means = (1.92 + 2.90 + 3.00 + 2.50 + 2.25) / 5
Mean of means = 2.515
Rounding off to the nearest hundredths, the mean of means is approximately 2.52.
Therefore, the mean of means for the given sample means is 2.52.
