A bag contains letter tiles. The following tiles are in the bag: E, A, E, T, N, G, P, T, and E. Assume you will randomly draw out letters from the bag, without looking, and then replace the letter into the bag.

What is the sample space of this event?

• {A, E, G, N, P, T}

• {A, E, T}

• {E, T}

• {N, G, E}

What would be the expected probability of getting this multiple choice question correct?

• 1/4

• 2/4

• 1/5

• 10%

What is: a combination of two or more simple events

• probability

What is: when the outcome of one event affects the outcome of another event

• dependent event

• independent event

• probability

• simulation

What is: the ratio of the number of times an event occurs to the total number of times that the activity is performed

• experimental probability

What is: the difference between the 3rd quartile and the 1st quartile in a set of data

• interquartile range

• range

• median

• mode

Match the following

• mean absolute deviation

• the average distance between each data value and the mean

• range

• the middle data value when the values are written in numerical order

• median

• the difference between the greatest data value and the least data value

• mean

• the data value that occurs the most often

• mode

• average, the sum of the data values divided by the number of items

Match the following.

• population

• the entire group of people or objects one wants to gather information about.

• random sample

• the values that divide the data in four equal parts

• probability

• A group from a population that accurately represents the entire population.

• representative sample

• the ratio of the number of favorable outcomes to the total number of possible outcomes

• quartiles

• a sample that is unbiased, every possible sample of the same size has an equal chance of being chosen
