Question

2. (6 points) Determine whether the value is a discrete random variable, continuous random vari able, or not a random variable. (a) (1 point) The exact time it takes to evaluate 123456789+987654321 (b) (1 point) The weight of a T-bone steak at Whole Foods Market (c) (1 point) The eye color of your MAT 150 classmates (d) (1 point) The number of your MAT 150 classmates now doing this midterm (e) (1 point) The "yes" or "no" response to a survey question (f) (1 point) The height of a randomly selected person

Explanation / Answer

Discrete random varaible - cant be measured in decimals

continous random variable - can be measured in decimals

random number - any whole number

keeping this in mind , lets answer the questions

a) we will get an exact number which would not be random , hence not a random variable

b) weight can be measured in decimals , such as 3.1kgs
hence continous random variable

c) the eye color can take values such as blue , black etc , hence not a random variable

d) number can be any number from 0 to 150 , however it can only be discrete , hence discrete random variable

e) yes , no cant be measured on a number scales , hence not a random variable

f) height can be measured in decimals , succh as 6.5 feet , hence continous random variable
