Advanced Algebra Statistics Quiz 1

The questions on a multiple choice test each have 6 answer choices. Which model can be used to simulate randomly selecting the correct answer on a 20 question multiple choice test?

• rolling a six-sided number cube 6 times
• rolling a six-sided number cube 20 times
• spinning a spinner with 4 equal sized sections 4 times
• choosing 1 marble in a bag of 20 different colored marbles

A certain brand of TV has a 50% chance of being defective. Which model could be used to determine the probability that when two TVs are chosen, they will both be defective?

• spin a spinner with 4 equal sections
• roll a die twice
• flip a coin twice
• flip a coin, then roll a die

As the number of trials increases the experimental probability approaches the theoretical probability.

• Yes
• No 
• Sometimes
• Roll Tide

A statistician calculates the probability of an event in an experiment. After a dozen trials of the experiment, the statistician finds that the theoretical probability and the experimental probability differ. What is the likely reason for this?

• The statistician hasn't completed enough trials of the experiment.
• The statistician made an error in their calculations.
• The statistician made an error in constructing their experiment.
• The statistician has completed too many trials of the experiment.
