Essay

Consider a multinomial experiment involving 160 trials 4 categories (cells). The observed frequencies resulting from the experiment are shown in the accompanying table. $$\begin{array} { | l | c c c c | } \hline \text { Categary } & 1 & 2 & 3 & 4 \\\hline \text { Frequency } & 53 & 35 & 30 & 42 \\\hline\end{array}$$ Use the 10% significance level to test the hypotheses: H₀: p₁ = p₂ = p₃ = p₄ = 0.25 vs. H₁: At least two proportions differ from their specified values.
