Clark repeatedly selected a ball from both bowls and recorded the results in a table. If there are 500 balls in Bowl B, what is the estimated difference in the expected number of white and red balls in Bowl B? (1 point) Responses 50 50 200 200 100 100 300

[AI-generated answer — Bot GPT 3.5]

The estimated difference in the expected number of white and red balls in Bowl B can be calculated by finding the difference between the percentages of white and red balls selected.

In Bowl A, 45 out of 100 balls selected were white, which means that 55 were red. In Bowl B, 60 out of 100 balls selected were white, which means that 40 were red.

Now, since there are 500 balls in Bowl B, we can estimate the number of white balls to be 60% of 500, which is 300. Similarly, the estimated number of red balls is 200.

Therefore, the estimated difference in the expected number of white and red balls in Bowl B is 300 - 200 = 100.

So, the answer is 100.
