Answer 1

To obtain random samples of restaurants, you can use a random number generator in your lab. The Math.random() function in JavaScript is one example of a random number generator. By generating random numbers and using them as indices, you can select restaurants from a list or database to create your samples.

Step-by-step explanation:

In this lab, you will be asked to pick several random samples of restaurants. To generate random numbers, you can use a random number generator. For example, you can use the Math.random() function in JavaScript to generate a random number between 0 and 1. To obtain a sample of restaurants, you can use the random numbers as indices to select restaurants from a list or database.

Here is an example procedure:

1. Generate a random number between 0 and 1 using a random number generator.
2. Multiply the random number by the total number of restaurants to obtain a random index.
3. Round down the random index to the nearest whole number.
4. Select the restaurant at the rounded index from the list or database.
5. Repeat steps 1-4 to obtain multiple random samples.

Based on the procedure described, you can list the restaurants in the sample you obtained.
