Solution
Solution Steps
To complete the table, we need to calculate the values of \(\hat{q}\) using the formula \(\hat{q} = 1 - \hat{p}\) for each given \(\hat{p}\). Then, compute the product \(\hat{p q}\) for each pair of \(\hat{p}\) and \(\hat{q}\). Finally, identify the value of \(\hat{p}\) that gives the maximum value of the product \(\hat{p q}\).
Step 1: Calculate \( \hat{q} \) Values
For each value of \( \hat{p} \), we calculate \( \hat{q} \) using the formula:
\[
\hat{q} = 1 - \hat{p}
\]
The calculated values are:
For \( \hat{p} = 0.0 \), \( \hat{q} = 1.0 \)
For \( \hat{p} = 0.1 \), \( \hat{q} = 0.9 \)
For \( \hat{p} = 0.2 \), \( \hat{q} = 0.8 \)
For \( \hat{p} = 0.3 \), \( \hat{q} = 0.7 \)
For \( \hat{p} = 0.4 \), \( \hat{q} = 0.6 \)
For \( \hat{p} = 0.5 \), \( \hat{q} = 0.5 \)
Step 2: Calculate \( \hat{p q} \) Values
Next, we compute the product \( \hat{p q} \) for each pair of \( \hat{p} \) and \( \hat{q} \):
\[
\hat{p q} = \hat{p} \cdot \hat{q}
\]
The calculated products are:
For \( \hat{p} = 0.0 \), \( \hat{p q} = 0.0 \)
For \( \hat{p} = 0.1 \), \( \hat{p q} = 0.09 \)
For \( \hat{p} = 0.2 \), \( \hat{p q} = 0.16 \)
For \( \hat{p} = 0.3 \), \( \hat{p q} = 0.21 \)
For \( \hat{p} = 0.4 \), \( \hat{p q} = 0.24 \)
For \( \hat{p} = 0.5 \), \( \hat{p q} = 0.25 \)
Step 3: Identify Maximum \( \hat{p q} \)
The maximum value of \( \hat{p q} \) is found to be:
\[
\max(\hat{p q}) = 0.25 \quad \text{at} \quad \hat{p} = 0.5
\]
Final Answer
The value of \( \hat{p} \) that gives the maximum product \( \hat{p q} \) is \\(\boxed{0.5}\\).
