Compare the decision making process Scenario 1: You have to ensure that you are sustained and have sufficient food for the month. You have a fixed budget of R500. Outline how you will go about getting the groceries that you need. 110 Practical 4 2020 se Study 1: Random Number Generation Work through Section 5.4 of your Practical Guide. Consider a random variable x-Unif(120,152). Using our theoretical formulae, we can find the mean and variance of x as: Pandem Number Generation = E(x) = 120 + 152 = 136 Number of Variables = Var(x) = (152 - 1202 Number of Random Number: 50 - 85.3333 Distribution Uniform We may want to consider whether the mean Parameters and variance of samples of x values are close to the population mean and variance. This can Between 120 and 152 be done by generating a sample of x values from this uniform distribution. Let's consider a sample of size 50. Generate this sample using Bandom Seed: a seed value of 123. Output options Once the sample data is generated, we can Output Range: SASI calculate the mean and variance of this data.
