Final answer:
The subject of this question is Mathematics and the student is seeking information about the selection process based on test scores.
Step-by-step explanation:
The subject of this question is Mathematics. In the question, a company's website states that the top 10% of candidates who take the entrance test will be called for an interview. The student has just been called for an interview, and they want to know more about the test and the selection process.
To calculate the threshold score for the top 10%, we need to find the value at which 10% of the candidates score below. This can be done by finding the 90th percentile, which is the score separating the top 90% from the bottom 10%.
Once the threshold score is determined, all candidates who score higher than that value will be called for an interview.
