High School

A teacher has two large containers filled with blue, red, and green beads, and claims the proportion of red beads is the same in each container. One student's samples contained 13 red beads from the first container and 16 red beads from the second container. Let [tex]p_1[/tex] be the true proportion of red beads in container 1 and [tex]p_2[/tex] be the true proportion of red beads in container 2.

Which of the following is a correct statement for the conditions for this test?

A. The random condition is not met.
B. The 10% condition is not met.
C. The large counts condition is not met.
D. All conditions for inference are met.

Answer :

Final answer:

Without additional information about the total number of beads sampled from each container, we cannot verify if the large counts condition is met. The correct statement for the student's hypothesis test condition is that the large counts condition is not met.

Explanation:

The conditions for inference in hypothesis testing involve random, large counts, and 10% conditions, among others. In order to arrive at a correct conclusion for the student's question about whether the proportion of red beads is the same in two containers based on the samples taken, we need to assess the available information against these conditions. The question details do not provide sufficient information to evaluate the random and 10% conditions. However, we can assess the large counts condition, which states that the sample must be large enough that the counts of successes (red beads) and failures (non-red beads) are both at least 10.

The large counts condition is met if there are at least 10 red beads and at least 10 non-red beads in both samples. Since the samples contain 13 red beads and 16 red beads respectively, we would also need to know that there are at least 10 non-red beads in each sample to satisfy the large counts condition. Without this, we cannot conclusively determine if the condition is met. Therefore, based on the information given, we can't definitively claim that all conditions for inference are met, option D. The correct statement is the large counts condition is not met, option C, since we cannot confirm that there would be at least 10 failures as well based on the given information.
