Final answer:
To find the mean of the given data, add up all the values and divide by the total number of values. The mean of the given data is 3.5 toy whales.
Step-by-step explanation:
To find the mean of the given data, we add up all the values and divide by the total number of values.
Luca has 3 toy whales.
Niklas has 3 toy whales.
Finn has 5 toy whales.
Lena has 3 toy whales.
Adding up the number of toy whales, we get 3 + 3 + 5 + 3 = 14.
The total number of individuals (Luca, Niklas, Finn, and Lena) is also 4. So, we divide the total number of toy whales by the total number of individuals to find the mean: 14 / 4 = 3.5.
Therefore, the mean of the data is 3.5 toy whales.
