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?

Fill in the Blanks

Kelly randomly chooses a number 1-10. The probability that it is a number less than 3 is

.

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.
