The penguins currently living on an island are of two types, Chinstrap penguins and Gentoo penguins. The range of the heights of
velikii [3]

Answer:

The answer is "Option A"

Step-by-step explanation:

Using the range difference to calculate the maximum and minimum value.

The range of the chinstrap penguins are:  

R(c) = Max(c) - Min(c) = 13.2

The range of the Gentoo penguins are:

 R(g) = Max(g) - Min(g) = 15.4

For point A:

Max(c) = x\\\\Max(g) = x + 5.8\\\\R(c) = x - Min(c) = 13.2 \to  x = 13.2 + Min(c)\\\\R(g) = x + 5.8 - Min(g) = 15.4 \to  x = 9.6 + Min(g)

equate both of them

13.2 + Min(c) = 9.6 + Min(g)Min(g) - Min(c) = 3.6

It indicates that Min(c) surpasses Min(g), whereas Max(g) exceeds Max (c).

Therefore, the Max is picked for g for all penguins and the minimum is picked for c.    

Range of all penguins = Max(g) - Min(c) = x + 5.8 - x + 13.2 = 19

Therefore, it will be determined as the option.

For point B:

In estimating the range the median height cannot help.

For point C:

In order to calculate the variety, the connection between both the mean height cannot be sued.
