To simulate the random selection of 50 adult consumers using a random digit generator, we need to generate 50 random integers and map them to the two possible outcomes based on the given probability. The correct approach is to generate random integers from 1 to 100, where integers 1 to 79 represent "recognizing the brand name" (since the probability is 0.79), and integers 80 to 100 represent "not recognizing the brand name."
We generate 50 random integers between 1 and 100. Each integer represents a consumer's response to recognizing the brand name.
We map the integers to two outcomes based on the given probability:
- Integers from 1 to 79 represent "recognize" (since \(0.79 \times 100 = 79\)).
- Integers from 80 to 100 represent "not recognize".
Given the generated integers:
\[ \{93, 38, 71, 24, 8, 82, 90, 23, 44, 39, 11, 57, 18, 96, 17, 32, 14, 83, 47, 10, 21, 65, 56, 53, 92, 94, 86, 16, 56, 37, 38, 82, 20, 39, 82, 36, 85, 68, 43, 72, 73, 29, 21, 90, 82, 80, 13, 98, 4, 93\} \]
We map these integers to the outcomes:
\[ \{\text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"not recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"not recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"recognize"}, \text{"not recognize"}, \text{"not recognize"} \}
The correct procedure for using a random digit generator to simulate the random selection of 50 adult consumers is:
\[
\boxed{\text{A}}
