A group of 824 statistics students enrolled at a private 4-year university were asked to write down a random integer between 1 and 20. Very few people chose the number 1 (less than 1%.) The most common numbers were 7 (10%), 13 (11%), and 17 (13%.) How effective are students at generating random numbers

Final answer:

Based on the given data, students are not very effective at generating random numbers.

Step-by-step explanation:

Based on the given data, it appears that the students are not very effective at generating random numbers. This is indicated by the fact that very few students chose the number 1, which is less than 1% of the total. Additionally, the most common numbers chosen were 7, 13, and 17, indicating a lack of randomness.

Answer:

Since the frequency of the numbers vary, the students are not effective at generating random numbers.

Step-by-step explanation:

If they were effective, all the numbers should have around the same probability of being generated.

Between 1 and 20 there are 20 numbers, so the frequency of each number should be around 100%/20 = 5%.

Since the frequency of the numbers vary, the students are not effective at generating random numbers.
