    Hello!! I thought I got the idea of calculating the expected values in the ISD test. I would have thought for question 12.9)iii) they were: 0, 0.18, 1.26, 3.06, 3.06, 1.26, 0.18, 0.
    Answers given are 0.01, 0.19, 1.22, 3.07, 3.07, 1.22, 0.19, 0.01. There answers are not that far off but there is obviously something I am missing. Could someone explain to me where I am going wrong?

    Thank you!!
