Mandrake Falls High School is experimenting with a weekend course in laboratory techniques. Of the 200 students enrolled in
lab classes at Mandrake, only 78 have been able to take the techniques course. Mandrake is interested in evaluating the
course's effectiveness in propagating safety in the laboratories.
During regular lab classes, lab instructors have recorded harmful lab incidents: accidents, misuse of lab equipment, etc. The
school is looking at the data and examining two variables: laboratory performance ("involved in no incident", "involved in
exactly one incident", or "involved in 2+ incidents") and status regarding lab 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 (f); the second number is the expected cell frequency
(E) under the assumption…
You may need to use the appropriate technology to answer this question.
An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were us
blocks in the experiment. The data obtained follow.
