Scribe Post- October 27- Period 1- Elizabeth C

The first thing we did in class was go over Homework 5. The big ideas for that were:

• As the number of people polled goes up, the percent that was in favor also went up


• The largest bars in the probability graph are the ones closest to the true proportion

Then we learned about the Central Limit Theorem:

Normal Distribution-

• Based on mean and Standard Deviation
• Represents probability of getting a result in an interval
• 68% of results fall within 1 deviation
• 95% will fall within 2 deviations

Inflection Point: The point where the curve switches from Concave up to Concave down.

Continuous Probability Distribution: When every point on the graph has a value(Like a bell curve)

Discrete Probability Distribution: When nothing happens between points (like a bar graph)

After this discussion, we did Deviations of Swinging while Mr. Marchetti checked the rest of the homework (Homework 12, 1, 2, 3 and the rational functions worksheet 380)

After that we whipped out the TI-nspires and did Graphing Distributions

Homework:

1. Revisions Due Thursday
2. Homework 6 and 7
