Following Are Observed Frequencies $H _ { 0 } : p _ { 1 } = 0.35 , p _ { 2 } = 0.25$

Multiple Choice

Following are observed frequencies. The null hypothesis is $H _ { 0 } : p _ { 1 } = 0.35 , p _ { 2 } = 0.25$ , $p _ { 3 } = 0.1 , p _ { 4 } = 0.1 , p _ { 5 } = 0.2$ .
$\begin{array}{l|lllll}\text { Category } & 1 & 2 & 3 & 4 & 5 \\\hline \text { Observed } & 43 & 20 & 10 & 4 & 31\end{array}$
