Here are the solutions to the questions:

Question 18: The proportion of all stations in the area which carries oil cost is the sample proportion ( $\hat{p}$ ). Given: Total stations in sample ( $n$ ) = 56 Stations carrying the advertised brand ( $x$ ) = 20

Step 1: Calculate the sample proportion. $\hat{p} = \frac{x}{n} = \frac{20}{56}$ Step 2: Simplify the proportion. $\hat{p} = 0.35714$ Comparing this to the options, none match exactly. Let's re
