To determine whose results give a better indication of the proportion of white and red balls in each bowl, we need to consider the number of trials each person conducted.
Simon selected:
- Bowl A: 5 white balls, 15 red balls (Total = 20)
- Bowl B: 16 white balls, 4 red balls (Total = 20)
Total trials conducted by Simon = 20 (from both bowls)
Clark selected:
- Bowl A: 45 white balls, 55 red balls (Total = 100)
- Bowl B: 60 white balls, 40 red balls (Total = 100)
Total trials conducted by Clark = 100 (from both bowls)
Since Clark conducted a greater number of trials (100) compared to Simon (20), Clark’s results are likely to be a better indication of the actual proportions of white and red balls in each bowl. The larger sample size reduces the influence of random variation and can lead to more reliable and accurate estimates of the underlying proportions.
Therefore, the correct response is:
"Clark’s experiment. He conducted a greater number of trials than Simon."
