A statistically-minded toll collector wonders if drivers are equally likely to choose each of the three
lanes at his toll booth. He selects a random sample from all the cars that approach the booth when all
three lanes are empty, so that the driver's choice isn't influenced by the cars already at the booth.
Here are his results:
Lane
Left
Center
Right
Number of drivers
137
159
169
1.
+
Which of the following is the correct expression for the chi-square goodness-of-fit test in this
situation?

(a) x2 =
155
155
155
(137-155) (159-155): 169-155)
(b) x =
137
159
169
(w) x -
(137 -155)". (159-155)". (169-155)'
