Final answer:
To estimate the number of 8th graders on the A honor roll, we can assume that the proportion of 8th graders in the sample is the same as the proportion in the entire population. Using this assumption, we can calculate an estimated number of 8th graders on the A honor roll.
Step-by-step explanation:
To find out how many students on the A honor roll are 8th graders, we need to know the proportion of 8th graders in the sample. Without this information, we cannot determine the exact number of 8th graders on the A honor roll. However, if the sample is representative of the entire A honor roll population, we can assume that the proportion of 8th graders in the sample is the same as the proportion of 8th graders in the entire population.
If we assume that the proportion of 8th graders on the A honor roll is the same as the proportion of 8th graders in the sample, we can use the sample proportion to estimate the number of 8th graders on the A honor roll. Let's say the sample consists of 100 students and there are 20 8th graders in the sample. If we assume this sample is representative of the entire A honor roll population, we can use the ratio of the sample proportion to the population proportion to estimate the number of 8th graders on the A honor roll. In this case, the estimated number of 8th graders on the A honor roll would be 20 times the ratio of the sample size to the population size, which is 20 * (100/300) = 6.67. However, since the number of students cannot be fractional, we would round this number to the nearest whole number. Therefore, the estimated number of 8th graders on the A honor roll would be 7.
