Today we talked about determining sample sizes for mean confidence intervals
Today was a Khan workday to review all material about mean confidence intervals.
There were also two unit tests to practice the material from the unit so far
Today we focused on accurately finding Z-values to use for proportion intervals.

Today we created confidence intervals for sample proportions
Today we found how to find the number needed to sample to guarantee a certain margin of error.
Today we learned how to create an inference for a population mean
Today we studied how to find a normally distributed sample distribution from any type of distribution.
