degrees of freedom is now 11−1−1 = 9: there are 11 categories,
minus one because the total is known, minus another one because the
expectation uses an estimated value for λ.
•excellence question: Someone observes that the number of days with
no calls at all is quite high. Formulate a sensible null hypothesis
and test it. Interpret and give a plausible reason for your
finding.
