Classify the following random variables as discrete or continous.

1) The surface area of a randomly selected person's body.

2) The quantity of oil in a randomly selected oil spill in the sea.

3) The quantity of pots in a randomly selected restaurant kitchen.

4) The total cent value of all the coins in a randomly selected person's pockets.

Expert Solution

A discrete variable is a variable whose value is obtained by counting.

Examples: number of students present

number of red marbles in a jar

number of heads when flipping three coins

students’ grade level

A continuous variable is a variable whose value is obtained by measuring.

Examples: height of students in class

weight of students in class

time it takes to get to school

1) The surface area of a randomly selected person's body.

= contionous because values are obtained by measuring

2) The quantity of oil in a randomly selected oil spill in the sea.

= continous variable beacuse we need to measure oil with som measurement device.

3) The quantity of pots in a randomly selected restaurant kitchen.

= discrete vaiable since we have to count pots .

4) The total cent value of all the coins in a randomly selected person's pockets.

= discrete variable because we need to count all coins and then find value of total cents.

Classify each of the following random variables as discrete or continuous. a) The time left on a parking meter So, we want to ask do we COUNT the time left on the parking meter or do we MEASURE it. We measure the time, so measuring is continuous. b) The number of bats broken by a major league baseball team in a season We can count the number of physical bats there broken during a season. Since we can COUNT it,...

Question 1: Two jointly distributed discrete random variables Consider two discrete random variables X, Y , taking values in {0, 1, 2, 3} each (for a total of 16 possible points). Their joint probability mass function is given by fXY (x, y) = c · x+1 y+1 . Answer the following questions. (a) What is c? (b) What is the probability that X = Y ? (c) Derive the marginal probability mass functions for both X and Y . (d)...

Multivariable Calculus: Surface Area and Change of Variables Find the surface area of the surface given by z =18−2x−3y over the triangle with vertices: (0,0), (2,3), (4,1). Since this is not a type I or type II region, you will either need to divide the region into two regions or use a change of variables. x=(1/5)(u-2v) and y=(1/10)(3u-v) is a possible change of variables. I will upvote answers!
