Answer:
Explanation:
To find the value of P, we need to use the information that the median of the data is 19. The median is the middle value in a set of data when it is arranged in numerical order. The first step is to arrange the data in numerical order which is 6-12 12-18 18-24 24-30 30-36 36-42.
We know that n = 4+3+3+4+10+P = 24+P, where P is the number of students in the age group 36-42.
Since the median is 19, half of the total number of students (n) will have ages less than 19. Therefore, we need to find the number of students whose ages are less than 19. Since 4+3+3 = 10, we know that 10 students are less than 19 years old.
To find P, we need to subtract the number of students whose ages are less than 19 from n, which is 24+P.
n = 24+P
10 = 24+P
P = -14
The value of P cannot be negative, so the given data is not correct. There is missing information that is needed to solve this problem.
