Explain how to identify outliers using the interquartile range.

Sampling Distribution of P hat 1. Center P= mean of p hat 2. Spread Standard deviation of p hat = Square root over all (P(1P)/n) 3. Shape p hat is “normal” meaning n multiplied by p or n(1p) has to be greater or equal to ten. Should be bellshaped. General Margin of error: Confidence level multiplier multiplied by standard error Hoping that the statistic is not wrong by more than the margin of error guessed Statistic: Guessing the parameter. Never know how wrong you might guess Standard error: approximation of standard deviation of p hat P hat = square root over all (p hat (1p hate)/n) Confidence level population proportion 1. Statistic p h
