Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
The mean or expected value of the distribution of a discrete random variable is?
30.47
A discrete random variable can have only certain clearly separated values?
true.
Is the variable is discrete or continuous the number of keys on each student's key chain?
A random variable such as the number of keys on each student's key chain is discrete because you can list the possible values it can assume. If it was continuous one would not be list a continuous random variable because it would be impossible. The keys on the key chains would be discrete.
Is the exact time it takes to evaluate 27 72 discrete or continuous?
it is a continuous random variable
Is the gender of college students a discrete random variable a continuous random variable or not a random variable?
It is a discrete random variable.
What is the definititon of a discrete random variable?
The discrete random variable almost always arises in connection with counting.
Can the Poisson distribution be a continuous random variable or a discrete random variable?
True
A random variable that can assume only a finite number of values is referred to as?
That would be a discrete variable; or, in your case, it would probably be called a discrete random variable.
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?
Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
Is the random variable x equals 1 be stated that the random variable is discrete?
If x = 1 then X is not really a random variable but a constant.
Is the number of statistics students now reading a book discrete or continuous?
The random variable is discrete
What is meant by discrete random variable?
A discrete random variable is a variable that can only take some selected values. The values that it can take may be infinite in number (eg the counting numbers), but unlike a continuous random variable, it cannot take any value in between valid results.
What is the difference between a discrete and continuous random variable?
· A variable whose values are determined by the outcomes of a random experiment is called a random variable. A random variable is a discrete random variable if it can assume values, which are finite or countable infinite. For example, tossing of a die is a random experiment and its outcomes 1, 2, 3, 4, 5 and 6 are discrete random variable. When a coin is tossed, its outcomes head and tail are discrete random variable. Three coins are thrown; the number of heads is example of discrete random variable. Note that the outcomes need ot be integers or even numbers (eg colour of eyes). · If a random variable can assume every possible value in an interval [a, b], a< b, where a and b may be - infinity and + infinity respectively, for example, the points on number line between 0 and 1; Value of 'x' between 0 and 2; Number of heads on a coin when it is tossed infinite times.
The mean or expected value of the distribution of a discrete random variable is?
30.47
What is discrete probability distribution?
It is a function that gives the probabilities associated with the discrete number of values that a random variable can take.
