Consider a multinomial experiment involving n = 200 trials and k = 5 cells. The observed frequencies resulting from the experiment are shown in the following table: The null hypothesis to be tested is as follows.
H0 : p1 = 0.05, p2 = 0.25, p3 = 0.35, p4 = 0.20, p5 = 0.15.
Test the hypothesis at the 5% level of significance.
Null Hypothesis
A statistical hypothesis that assumes no significant difference or effect in a particular test, used as a starting point for experimentation.
Alternative Hypothesis
A hypothesis that suggests there is a difference between two or more sets of data, contrasting the null hypothesis.
