Unit 10 Review

Unit Test is Tuesday!

Topics to Study:

-Population vs Sample

-Calculating mean or proportion

-Methods of collecting data

-Calculating Probability

-Standard Deviation

Multiple Choice

If there are 36 successful outcomes in a sample with a size of 80, what is the sample proportion?

• 0.45

• 0.50

• 0.65

• 0.43

Open Ended

You spin a spinner with 4 sections: 1 yellow (Y), 1 purple (P), 1 red (R), and 1 blue (B).What is the sample space for one spin of this spinner?

Multiple Select

Alina, Robert, and Makayla are on the student council at their high school. They all want to go to a dinner where student council representatives from other schools will participate. However, only one student per school can go. How can a fair decision be made about who goes to the dinner?

• Roll a number cube. If the number is even, Alina wins. If the number is 1 or 3, Robert wins. If it's any other number, Makayla wins.

• Flip a coin twice. If both tosses are heads, Alina wins. If both are tails, Makayla wins. If one is heads and one is tails, Robert wins.

• Write each student's name on a slip of paper and put the slips in a bag. Randomly draw a slip of paper. The student whose name is on the paper wins.

• Roll a number cube. If it lands on 1 or 3, Alina wins. If it lands on 2 or 4, Robert wins. If it lands on 5 or 6, Makayla wins.

Multiple Choice

An English teacher has equal numbers of fiction, literature, and poetry books. Each day, she randomly selects one book to read from. She designs a simulation to estimate the probability that the next three books she selects are all literature.Which simulation design could she use to estimate the probability?

• Number cubeLet 1, 6 = literatureLet 2, 5 = fictionLet 3, 4 = poetryRoll the cube three times. Repeat.

• CoinLet heads (H) = literatureLet tails (T) = fiction or poetryToss the coin three times. Repeat.

• Number cubeLet odd number = literatureLet even number = not literatureRoll the cube three times. Repeat.

• Random digits from 0 to 9 Let 1, 2, 3 = literature Let 4, 5, 6 = fiction Let 7, 8, 9, 0 = poetry Select three random digits from 0 to 9. Repeat.
