Question
Table 3.10 from Huber and Gleu (2007) shows the number of no hitter baseball games that were pitched in the 104ball seasons between 1901 and 2004. For instance, the following data on the number of no-hitter baseball games that were pitched in the 104 baseball seasons between 1901 and 2004 are given in Huber and Glen (2007).
For instance, 18 seasons saw no no-hit games pitched; 30 seasons saw one no-hit game, etc. Use these data to model the number of no-hit games for a baseball season. Create a table that compares the observed counts with the expected number of no-hit games under your model (Table 3.10).

Explanation / Answer
Ho: There is no significant difference in the proportion of the number of games.
H1: at least one of the proportion of the number of games differs significantly
chisq= 62.46153846
p-value= 4.85893E-11 CHISQ.TEST(Oi, Ei)
with chisq=62.46 and p-value < 0.05, i reject ho and conclude that at least one of the proportion of the number of games differs significantly
# games Oi pi Ei= pi*N=Pi*104 (Oi-Ei)^2/Ei 0 18 0.125 13 1.923076923 1 30 0.125 13 22.23076923 2 21 0.125 13 4.923076923 3 21 0.125 13 4.923076923 4 6 0.125 13 3.769230769 5 3 0.125 13 7.692307692 6 3 0.125 13 7.692307692 7 2 0.125 13 9.307692308 SUM 104 1 104 62.46153846Related Questions
