The mean of the data set is 42.

<h3>What is Mean?</h3>

The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.

Given:

20, 32, 34, 36, 40, 42, 44, 48, 55, 65

Mean = 20+32+ 34+ 36+ 40+ 42+ 44+ 48+ 55+ 65/10

Mean = 416 / 10

Problem 2. A random variable has the following density function:

kolbaska11 [484]

If <em>f(x)</em> is a density function, then its integral over the entire real line should be 1:

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2(1-0.5x)\,\mathrm dx=(x-0.25x^2)\bigg|_0^2=2-1=1$

so yes, <em>f(x)</em> is indeed a density function.
