The average (arithmetic mean) of $$t$$ and $$y$$ is $$15$$, and the average of $$w$$ and $$x$$ is $$15$$. What is the average of $$t, w, x$$ and $$y$$? 

The mode of the observations $$5, 4, 4, 3, 5, x, 3, 4, 3, 5, 4, 3,$$ and $$5$$ is $$3$$. What is the median?

The mean of $$48, 27, 36, 24, x$$, and $$2x$$ is $$37.x =$$

Given, $$10, 18, 4, 15, 3, 21, x $$
 If $$x$$ is the median of the $$7$$ numbers listed above, which of the following could be the value of $$x$$?

The average of six numbers is 4. If the average of two of those numbers is 2, what is the average of the other four numbers?

The median of $$2, 7, 4, 8, 9, 1$$ is

For a collection of $$11$$ items, sum of all items is $$132$$, then the arithmetic mean is.

The mode of the data $$5, 5, 5, 5, 5, 1, 2, 2, 3, 3, 3, 4, 4, 4, 4$$ is

A random sample of 20 people is classified in the following table according to their ages

The following observations have been arranged in the ascending order. If the median of the data $$29, 32, 48, 50, x, x+2, 72, 78, 84, 95$$ is $$63$$, then the value of $$x$$ is ___________.
