Question
A multinomial experiment with \( k = 3 \) cells and \( n = 440 \) produced the data shown below.

\[
\begin{array}{|c|c|c|c|}
\hline
& \text{Cell 1} & \text{Cell 2} & \text{Cell 3} \\
\hline
n_i & 120 & 117 & 203 \\
\hline
\end{array}
\]

If the null hypothesis is \( H_0 : p_1 = 0.25, \; p_2 = 0.25, \; p_3 = 0.5 \) and using \( \alpha = 0.05 \), then do the following:

(a) Find the expected value of Cell 1.  
\[ E(\text{Cell 1}) = \boxed{} \]

(b) Find the expected value of Cell 2.  
\[ E(\text{Cell 2}) = \boxed{} \]

(c) Find the expected value of Cell 3.  
\[ E(\text{Cell 3}) = \boxed{} \]

(d) Find the test statistic.  
\[ \chi^2 = \boxed{} \]

(e) Find the rejection region.  
\[ \chi^2 > \boxed{} \]
