Here are the solutions to your questions. 3.1 Use the above data to complete the frequency table. The frequency table is not provided, so the frequencies for each fast-food preference are listed below: Beef Burger (BB): 5 King Pie (KP): 6 Chicken and Mayo Sandwich (CMS): 3 Kota (KT): 9 Vetkoek (VK): 7 3.2 Determine the sample size. The sample size is the total number of students surveyed. Step 1: Sum the frequencies of all preferences. Sample size = 5 + 6 + 3 + 9 + 7 Sample size = 30 The sample size is 30. 3.3 If a student is chosen randomly, what is the probability of choosing a student who prefers to eat a Kota? Express as a percentage. Step 1: Identify the number of students who prefer Kota and the total sample size. Number of students who prefer Kota = 9 Total sample size = 30 Step 2: Calculate the probability. Probability (Kota) = Number of students who prefer KotaTotal sample size Probability (Kota) = (9)/(30) Step 3: Convert the probability to a percentage. Probability (Kota) = (9)/(30) × 100\% Probability (Kota) = 0.3 × 100\% Probability (Kota) = 30\% The probability of choosing a student who prefers Kota is 30\%. 3 done, 2 left today.
