- Selection of the samples based on the convenience of the researcher is an example of __________. random sampling nonrandom sampling inconvenience sampling non-statistical samplingRandom Processes and Relative Frequency Part 1: A six sided die is rolled repeatedly. The possible equally likely outcomes are 1, 2, 3, 4, 5, or 6. The graph represents the relative frequency of 4's that occur (number of 4's divided by the total number of rolls) versus the number of times the die was rolled for the first 20 rolls. The table shows these values, and in addition, the total number of 4's after each number of rolls. Use this information to answer the questions below.
