Confidence Intervals

This is Wilson scribing again.
Some people might be missing the first half of next week for the Provincial English Language Arts Exam. I write the exam in the morning, so it does not actually affect this math course.
Enough about that, now to some work.
Today we learned about Confidence Intervals “Predicting the mean of a sample”
The main idea is to be able to predict with varying level of accuracy (Confidences) the mean of a sample.
Usually levels of confidence are measured at 90% 95% and 99%.
Mr. Maxx’s nice diagrams might show it even better than I could tell you though.

I hope this helps you (all you viewers out there in the electronic world) to understand.
