When rolling a pair of fair dice, the probability of rolling a total point value of 7 is 0.17 . If you rolled a pair of dice 1,000 times and the point value of 7 appeared 723 times, what would you probably conclude?
a. This is not so unlikely as to make you doubt the fairness of the dice.
b. Although not impossible, this outcome is so unlikely the fairness of these dice is questionable.
c. Since the total point value of 7 has the highest probability of any event in the sampling distribution, this is anextremely likely outcome.
d. It is impossible for this to happen if the dice are fair.
Question 2Which of the following best describes knowing the relative frequency of every possible event in a population?
a. A probability distribution
b. A population distribution
c. A frequency distribution
d. A sample distribution
Question 3An event's relative frequency in the population equals
a. 100.
b. the average number of times an event occurs in the population.
c. the odds of the event.
d. the probability of the event.
Question 4How is the relative frequency of an event defined?
a. Since the z-value does not fall within the region of rejection, we should not conclude that this sample mean represents some other population
b. The average number of times an event occurs in the population of events
c. The proportion of times an event occurs in the population of events
d. The proportion of times all events occur
Question 5What is the essence of all inferential statistics?
a. Making inferences about the characteristics of samples
b. Making sure you choose a sample representing the population
c. Knowing the characteristics of the population
d. Using sample data to make statements about the scores and relationships in the population
