Suppose that computer literacy among people ages 40 and older is being studied and that the accompanying tables describes the probability distribution for four randomly selected people, where x is the number that are computer literate. Is it unusual to find four computer literates among four randomly selected people?
To determine whether it is unusual to find four computer literates among four randomly selected people, we need to examine the probability distribution given in the accompanying table.
However, since you haven't provided the table or any specific information about the probabilities, I am unable to calculate the exact probabilities. Nonetheless, I can guide you through the general process of determining whether an event is unusual based on a probability distribution.
1. Identify the probabilities: Look at the table and determine the probabilities assigned to each possible outcome (e.g., 0, 1, 2, 3, or 4 computer literates).
2. Calculate the probability of four computer literates: Find the probability associated with the outcome of four computer literates. Depending on the distribution, this may involve adding up individual probabilities or observing the corresponding cell in the table.
3. Evaluate the probability: If the probability of four computer literates is very low (e.g., less than 5% or 0.05), then it can be considered unusual. However, if the probability is relatively high, it would not be deemed unusual.
Keep in mind that the term "unusual" can be subjective, and the threshold for what is considered unusual may vary depending on the context or specific criteria set for the study.
If you provide the specific probabilities from the table, I can assist you further in determining whether it is unusual to find four computer literates among four randomly selected people.
