a spinner with eight equal sectors is spun 20 times. the results of the simulation are shown in a dot - plot. which dot plot models an unfair data - generating process?

a spinner with eight equal sectors is spun 20 times. the results of the simulation are shown in a dot - plot. which dot plot models an unfair data - generating process?

Answer

Explanation:

Step1: Understand fair - unfair concept

In a fair spinner with 8 equal sectors, each sector has an equal probability of being landed on when spun multiple times. So, the frequencies of the results should be relatively evenly distributed.

Step2: Analyze dot - plots

For a fair process, the number of dots above each number (representing a sector) should be somewhat similar. In the last dot - plot, the dots are concentrated mainly on 6, 7, and 8, and there are very few dots on 1 - 5. This indicates that some outcomes are much more likely than others, which means the data - generating process is unfair.

Answer:

The last dot - plot (the one with most dots on 6, 7, 8 and few on 1 - 5) models an unfair data - generating process.
