The median score was 22 for both samples. Which of the following statements is true about the mean ACT for each sample?

The mean score for the sample from school A is equal to the mean score for the sample from school B.

The mean score for the sample from school A is less than the mean score for the sample from school B.

The mean score for the sample from school A is greater than the mean score for the sample from school B.

We cannot determine the relationship between the mean ACT scores without knowing the actual scores on the exam.

We cannot determine the relationship between the mean ACT scores without knowing the actual scores on the exam, even though we know that the median score is the same for both samples.

The median is the middle value of a dataset, and it does not necessarily reflect the mean or average score. The mean can be affected by extreme values, or outliers, in the dataset, which may not be reflected in the median.

Therefore, we cannot conclude anything about the relationship between the mean ACT scores of the two samples based solely on the information that the median score is the same for both samples. We would need to know the actual scores on the exam in order to determine the mean ACT score for each sample and compare them.
