BUS 204 Week 6  Quiz | MiraCosta College

Question 1

The time required to assemble two components into a finished part is recorded for each employee at the plant. The resulting random variable is an example of a continuous random variable.

True  

False

Question 2

When a market research manager records the number of potential customers who were surveyed indicating that they like the product design, the random variable, number who like the design, is a discrete random variable.

True  

False

Question 3

The following probability distribution has been assessed for the number of accidents that occur in a Midwestern city each day:

Accidents            Probability

0              0.25

1              0.20

2              0.30

3              0.15

4              0.10

This distribution is an example of:  

a continuous probability distribution.  

an expected value distribution.  

a discrete probability distribution.  

a uniform distribution.

Question 4

Which of the following is not a condition of the binomial distribution?

The standard deviation is equal to the square root of the mean.  

Two possible outcomes for each trial  

The trials are independent.  

The probability of a success remains constant from trial to trial.

Question 5

If a study is set up in such a way that a sample of people is surveyed to determine whether they have ever used a particular product, the likely probability distribution that would describe the random variable, the number who say yes, is a:

binomial distribution.  

uniform distribution. 

Poisson distribution. 

continuous distribution.

Question 6

Assuming that potholes occur randomly along roads, the number of potholes per mile of road could best be described by the:

binomial distribution.  

continuous distribution  

hypergeometric distribution.  

Poisson distribution.

Question 7

The Excel function for the Binomial Distribution when we are looking for the probability that x is less than or equal to 3, or P(x≤≤3) is:    

=BINOM.DIST(x,n,p,True)  

=BINOM.DIST(x,n,p,False)  

=1 - BINOM.DIST(x,n,p,True)  

=1 - BINOM.DIST(x,n,p,False)
