Dear Students,

Nice to work with you today! We did a quick quiz on “Exponential Growth” and reviewed percentages. Please check the notes for your review, and finish Test Innovators homework before May. 2nd. 

There will be no school in the following two weeks. Enjoy your spring break, and see you on May 3rd! We will take DSAT#9 when we are back. 

Warm regards,
Ms. Li

Dear Students,

It’s so nice to work with you~ Today we reviewed problems in DSAT#8 and learned Inference from sample statistics and margin of error. Here are the notes for your review. 

Key concepts:

1. random sampling

2. the larger the sample size, the smaller the margin of error

Please finish the assignments on Test Innovators, and fill out the Question Form to share your problems with me. We will learn L16: Percentages and take a “pop quiz” next week.

See you on soon～

Best,

Ms. Li
