Step 1 :Calculate the four values: \(n_{1} \hat{p}_{1}\), \(n_{1}(1-\hat{p}_{1})\), \(n_{2} \hat{p}_{2}\), and \(n_{2}(1-\hat{p}_{2})\)
Step 2 :For \(n_{1} \hat{p}_{1}\), calculate \(26 * 0.923\) to get \(23.998\)
Step 3 :For \(n_{1}(1-\hat{p}_{1})\), calculate \(26 * (1-0.923)\) to get \(1.992\)
Step 4 :For \(n_{2} \hat{p}_{2}\), calculate \(38 * 0.789\) to get \(29.982\)
Step 5 :For \(n_{2}(1-\hat{p}_{2})\), calculate \(38 * (1-0.789)\) to get \(8.018\)
Step 6 :Round these four values to three decimal places: \(n_{1} \hat{p}_{1} = 24.000\), \(n_{1}(1-\hat{p}_{1}) = 2.000\), \(n_{2} \hat{p}_{2} = 30.000\), and \(n_{2}(1-\hat{p}_{2}) = 8.000\)
Step 7 :Since all four values are greater than or equal to 5, the normal distribution can be used to compare the population proportions. \(\boxed{\text{Yes}}\)
