Simon’s Results

This table shows the number of white and red balls Simon selected from Bowl A and Bowl B.
Number of White Balls Selected Number of Red Balls Selected
Bowl A 5 15
Bowl B 16 4
Clark’s Results

This table shows the number of white and red balls Clark selected from Bowl A and Bowl B.
Number of White Balls Selected Number of Red Balls Selected
Bowl A 45 55
Bowl B 60 40
Bowls A and B contain a number of white and red balls. Simon and Clark repeatedly selected a ball from both bowls and recorded the results in a table. Whose results will give you a better indication about the proportion of white and red balls in each bowl? Explain your answer.

Neither; they conducted the same number of trials.
Neither; they conducted the same number of trials.

Both results can be used, as they performed the experiment at random.

To determine whose results give a better indication of the proportion of white and red balls in each bowl, we can compare the number of trials conducted by Simon and Clark.

From the data provided:

  • Simon’s Results:

    • 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 + 20 = 40

  • Clark’s Results:

    • 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 + 100 = 200

Clark conducted significantly more trials than Simon (200 trials compared to 40). With a larger sample size, Clark's results will provide a more accurate representation of the proportions of white and red balls in each bowl.

Thus, the correct response is:

Clark’s experiment. He conducted a greater number of trials than Simon.
