- Total number of students?
Thank - you
in advance
What did you get for the number of students? This is a very simple problem that requires only that you keep a running total of the frequencies of the shoe sizes. BTW, I agree with the book's answer.Phisico said:Problem Statement: I got the different answer as in the book, explain please if I am wrong.

It looks like you were adding the shoe sizes instead of the frequencies.Phisico said:Problem Statement: I got the different answer as in the book, explain please if I am wrong.

Must have had Hervé Villechaize in the classberkeman said:Who in the world wears a size 2 shoe?
Looks like the problem designer failed to take heed of the fact (among others he apparently disregarded) that the specification "third year maths class" should bias the distribution (of students over/across shoe sizes) to the right.berkeman said:Who in the world wears a size 2 shoe?
HEY, *I'M* supposed to be the nitpicker in chief on this forumDaveC426913 said:Some assumptions happening here: who says they have the same size on each foot?
There are at least 14 students in the class.
Perhaps they wear size 4, but have only one shoe.berkeman said:Who in the world wears a size 2 shoe?
The total number of students in a class can be determined by counting the number of students present in the class or by checking the class roster provided by the school or instructor.
No, the total number of students in a class can vary depending on factors such as enrollment, class size limits, and student attendance.
Yes, the total number of students in a class can change throughout the school year due to factors such as students dropping or adding the class, transferring to another school, or being absent for an extended period of time.
Knowing the total number of students in a class is important for various reasons, such as determining the student-teacher ratio, planning classroom activities, and ensuring that all students have access to necessary resources and materials.
Yes, the total number of students in a class can affect the learning environment. A larger class size may make it more challenging for the teacher to provide individual attention to each student, while a smaller class size may allow for more personalized instruction and a better learning experience.
