A medical researcher claims that 60% of people with shellfish allergies do not have their first allergic reaction until adulthood. This value seems suspicious to a class of statistics students, so they ask an SRS of 30 adults with a shellfish allergy when they experienced their first allergic reaction. Fourteen of the adults experienced their first allergic reaction in adulthood. To see if this result is surprising, the class conducts a simulation to estimate the probability of obtaining a sample result as low as the one in their sample.

Let 0–5 represent "adulthood” and 6–9 represent "before adulthood.”

06422, 61491, 26030, 87247, 20503, 68603.

Using the line of random numbers, how many "adulthood” responses are in the first trial of the simulation?

5
10
15
20

Respuesta :

Answer: 5

Step-by-step explanation:

Using the line of random numbers provided, we can see that the first trial of the simulation resulted in 5 "adulthood" responses. To determine this, we need to count the number of times that the digits 0, 4, 2, and 2 appear in the trial. These digits represent "adulthood" according to the coding system provided. We can see that these digits appear 5 times in the first trial of the simulation.
