Flip your coin 20 times and record the number of heads you get. Repeat this process 4 more times. Record your results in the table below. 3. You performed 20-coin flips 5 times. Based on your data alone, what range of values would you predict for the number of times the coin would land on heads? 4 How does your prediction compare to the range of values you described from the class’s data? 5. If 1,000 people flipped a coin 20 times, how might that change your prediction from the range for the class’s data? 6.

Explain your reasoning.Simulate the drawing many times to find some possible results.Cut a piece of paper into 25 equal-sized pieces. On 10 on the pieces of paper, write “graduating class.” On the other 15 pieces of paper, write “other classes.” Fold the papers in half and mix them up.Take turns with your partner to draw 8 pieces of paper and record the number of students chosen that are in the graduating class.Repeat this process 4 more times.Create a dot plot that shows the number of students chosen from the graduating class by all of the students in your class. Based on the dot plot, do you think it is reasonable that the principal selected the students for the interview at random and still chose 5 of the 8 students who are in the graduating class?

Mai gathers a random sample of 30 students at her school and asks them whether they would be willing to start and end the school day 1 hour later than usual. 27 of the students agree that this would be a good idea. Mai goes to the principal and says, “Exactly 90% of students think it’s a good idea to start and end the school day an hour later than usual!” What is wrong with this statement? 6. After collecting more data, Mai reports that the proportion of students who think it is a good idea to change school hours is 90% with a margin of error of 3%. What does this mean?
