Question

Let S represent the number of randomly selected adults in a community surveyed to find someone with a certain genetic trait.The random variable S follows a geometric distribution with mean 4.66. Which of the following is a correct interpretation of the mean?answer choicesA value randomly selected from the distribution of S is expected to be 4.66.In repeated sampling from the distribution of S, the average of the values will approach 4.66.For a sample of values randomly selected from the distribution of S, the average of the sample will be 4.66.The probability is 0.66 that a value randomly selected from the distribution of S will be close to the mean.For a sample of values randomly selected from the distribution of S, the average of the sample will vary from the population mean by no more than 4.66.
