Consider a multinomial experiment involving 100 trials and 3 categories (cells). The observed frequencies resulting from the experiment are shown in the accompanying table. $$\begin{array} { | l | c c c | } \hline \text { Categary } & 1 & 2 & 3 \\\hline \text { Frequency } & 38 & 35 & 27 \\\hline\end{array}$$ Use the 5% significance level to test the hypotheses H₀: p₁ = 0.45, p₂ = 0.30, p₃ = 0.25 vs. H₁: At least two proportions differ from their specified values.
