Question

Discrete random variables: You are studying the number of times that something happened (counted, not measured). For example, the number of times that you flip a coin and it comes up "heads".

Continuous random variables: The outcomes are measured, not counted. For example, how tall a plant grows (in centimeters) when it has fertilizer added.

please give an example of at least one discrete random variable and one continuous random variable that a researcher might study in your intended career field. How are they different? (career field in speech therapy)

Answer #1

**Answer:**

1) An irregular coin (? (?) = ?? (?)) is thrown 3 times. ?
discrete random variable; ? = "number of heads - number of tails"
is defined. Accordingly, ? is the discrete random variable
number of heads - number of posts
a) Find the probability distribution table.
b) Cumulative (Additive) probability distribution table; ?
(?)
c) Find ? (?≥1).

13. Examples of discrete random variables include which of the
following? (I) The number of clicks an online advertisement
receives (II) The amount of oxygen in a certain room. (III) The
number of people on a flight from LA to Australia (IV) The number
of traffic accidents on a particular stretch of I-80 in 2012
14. The expected value is essentially a _____________of the
possible outcomes for the random variable. The weights are the
corresponding probabilities for those possible outcomes....

Discrete Random Variables have either a finite or countable
number of values.
True
False
An example of continuous variables is bushels of wheat per
acre.
True
False
The Mean Value of a discrete probability distribution (denoted
by mu is a weighted average of the x-values AND represents the
average values of all possible outcomes.
True
False

________II. The following table shows the population probability
distribution of x, the random variable representing the price per
ticket, in dollars, for 20 upcoming concerts at a certain
community’s civic center.

Which of the following situations
do notinvolve a discrete random variable? There may be
more than one answer. (Note that you are only asked to identify the
type of variable; you do not need to try to solve any of
them.)
The average length of time a call to company
Q's helpline takes is 8.53 minutes. Assuming that the times are
normally distributed and there is a 50% chance that a call lasts
for less than 8.53 minutes, estimate the standard...
