Question

The number of defective items in a manufacturing process is an example of _________ data.

a	discrete
b	continuous

Answer 1

Definitions of Discrete and Continuous random variable

1)Discrete Random Variables. ... A discrete variable is a variable which can only take a countable number of values. In this example, the number of heads can only take 4 values (0, 1, 2, 3) and so the variable is discrete.

2) A continuous random variable is a random variable where the data can take infinitely many values. For example, a random variable measuring the time taken for something to be done is continuous since there are an infinite number of possible times that can be taken

Here in the given problem no of defective items in a manufacturing process,

Numbers of defective items in a manufacturing process are either finite or countable.As for any manufacturing process we have fixed value of number of defective items or we can say that for any manufacturing process contains fixed number of defective items.

So the number of defective items in a manufacturing process is an example of Discrete data/ random variable..
