PROJECT SUMMARY 5
Using data from the Lefty-Righty Experiment:
Estimate the percentage of left-handed people in the sampled population
Explore why some people write faster than others.

7. STUDENT LEARNING OUTCOMES
(“I will” statements)
10:39:51 6
I will learn how to estimate confidence intervals
I will learn how to use the binomial distribution to check if collected data seem unusual given an assumed proportion
I will use the one-sample z-test to test the claim the percentage of left-handed people sampled match the population at large
I will test if the collected data are sampled from a normally distributed population
I will use the t-test for two samples to conduct a hypothesis test about why some people write faster than others.

SORTING DATA 7
This scatter plot determines how many left-handed people are in the sample.

9. 9
10:39:51
Too many left-handed?
Assuming 10% of people are left-handed, then the probability
of having 1 out of 16 people be left-handed is

10. Estimate the percentage of left-handed people
10:39:51 8
Estimate the percentage of left-handed people
From eight sample sets, we are 95% confident
that 10% of people are left handed.

11. Z-test for one sample 10 Ho: p = 0.1 Ha: p ≠ 0.1
10:39:51 10
Ho: p = 0.1
Ha: p ≠ 0.1
Conduct a z-test about the hypothesis of 10% of people are
left handed.

12. 10:39:51
Normal Quantile Plot 11
To check if data are from a normally distributed population.

13. 10:39:51
T-test for two samples 12
To test the hypothesis if people who drink coffee can write faster
than those who don’t.

PROCEDURES 14
Have students do the lefty-righty experiment in class as an example. Then discuss potential topics.
Divide students in groups of 4. Have each group choose a topic.
Each student should give this experiment to at least 16 people (8 per category.) Students have to submit their data by a deadline. If not, other students can submit extra data and get their points.
Give the deadline to submit the confidence interval.
Spend about 15 minutes in class to find the percentage of left-handed people based on the work in step 5.
Give the deadline to submit the group work for testing the percentage and the group’s claim.
Course materiel connecting z- and t- tests
Write individual reports. Each student analyzes their own data (small N) and compares it to their group work (large N).
Have students do the lefty-righty experiment in class as an example. Then discuss what potential topics are.
