Question
A traffic office in a country was in charge of a study where the safety of passengers in
different types of cars was examined. Three models were examined; small cars, minivans and
SUVS and six cars in each category were inspected. A special traffic accident simulator was
used in the study and the pressure on the drivers' heads was measured. Umferðarastofa
wanted to investigate whether there was a difference in the average pressure on the head
during a collision in these three types of cars and used a variance analysis for this purpose.
Failed to complete the square sum table, which can be seen below.
