During regular lob dosses, lab instructors have recorded harmful lab Inddents: accidents, misuse of lab equipment, etc. The school is looking at the data and examining two variables: aborativy performance ("involved In no Incident", "Involved In exactly one Indent", or "Involved In 2+ Incidents ) and status regarding lob techniques course ("took the techniques course" or "didn't take the techniques course"}. The contingency table below gives a summary of the data that have been gathered so far. In each of the 6 cells of the table are three numbers: the first number Is the observed cell frequency (]; the second number Is the expected cell frequency () under the assumption that there is no relationship between students" laboratory performances and whether or not they took the techniques course; and the third number is the following value. Observed cell frequenty - Expected cell frequency) Expected cell frequency The numbers labeled "Total" are totals for observed frequency Part 1 Fill In the missing values in the contingency table. Round your expected frequencies to two or more decimal places, and round your values to three or more decimal places.
