Pamela called 9 repair shops for quotes for auto repairs. The prices are $139, $150, $345, $99, $167, $155, $140, $200, and $160. She calculates to find there are no outliers in the data.

Answer the following statement true (T) or false (F)


False

$99, $139, $140, $150, $155, $160, $167, $200, $345
Median $155, lower quartile $139.50, upper quartile $183.50;
interquartile range 183.50 - 139.50 = $44; 139.5 - 44 = $95.50 and  183.50 + 44 = $227.50
Anything below $95.50 and above $227.50 are outliers so $345 is an outlier.
