Clark's experiment. He conducted a greater number of trials than Simon.
Explanation: Clark's results, which involve a higher number of trials (100 total selections compared to Simon's 36), are likely to provide a better indication of the true proportions of white and red balls in each bowl due to the larger sample size. A greater number of trials tends to reduce sampling error and gives a more accurate representation of the population being studied.
