Good morning In the solutions for this part of the question the sum of the observed frequencies is not 708, after the data has been cut down to only 19 rows. It is showing that there were 25 observations of 18 or more waiting days, but I think it should be 29. Can you confirm if this is correct please? Thank you
Hello You're right, it should be 29. There is a mistake in the function. The expected number calculations are also not quite right. A correction will be added to the CS2 corrections document. Andy
