X and Y are modeled inflation rates, in terms of %, for two different countries at the end of a five-year period. X is uniformly distributed on the interval (0, 10). Y, given X = x is uniformly distributed on the interval (0, x). Calculate Cov(X, Y).

The value of Cov (X, Y) is 25/6.

Step-by-step explanation:

It is provided that:

The probability density functions are as follows:

Then the value of f (x, y) will be:

Then f (y) is:

Compute the value of E (X) as follows:

Compute the value of E (Y) as follows:

Compute the value of E (XY) as follows:

Compute the value of Cov (X, Y) as follows:

Thus, the value of Cov (X, Y) is 25/6.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
