Question

Claudia's calculator will generate random numbers. She sets it to generate a number from 1 to 5 one hundred times. She then calculates the relative frequency of each number. Outcome 1 2 3 4 5 Relative frequency 0.19 0.21 0.18 0.21 0.21 Select from the drop-down menus to correctly complete each statement. The relative frequencies in the table are . A uniform probability model a good model to represent probabilities related to the numbers generated by Claudia's calculator. Therefore, the theoretical probability that any one number is chosen is likely .

Answer 1

The relative frequencies in the table are is: Very different. A uniform probability model: is a good model to represent probabilities related to the numbers generated by Claudia's calculator. Therefore, the theoretical probability that any one number is chosen is likely: 0.20.

Answer 2

The answers are in bold

The shown relative frequencies are 0.18, 0.19, and 0.21, which is pretty close to 0.19 - 0.20. From there you can tell that they are reasonably close to equal.

That means that the probailities are close to uniform and => A uniform propabililty model IS a good model to represent probabilities related to the numbers generated by Claudia's calculator. 

Therefore, the theoretical probability that any one number is chosen is likely 0.2.
