Question
![1. In a survey conducted recently by ESPN-LA radio in an attempt to find the proportion of residents of LA on being a Lakers fan or not, the result of this survey is given in the table below:
\[
\begin{array}{|c|c|}
\hline
\text{Females} & \text{Males} \\
\hline
x_1 = 20 & x_2 = 26 \\
n_1 = 42 & n_2 = 54 \\
\hline
\end{array}
\]
a. Find the pooled proportion \( \bar{P} \).
b. Find a 95% confidence interval for the difference between the two population proportions \( P_1 - P_2 \) using the table from above.
