In a large statistics course, it has been historically found that 30% of all students receive either an A or B ; 40% receive a c ; and 30% receive a D or lower. one class of 40 students complain that they were harshly graded in the examination as l0 students received A or B ; 17 received a C ; and the rest received a D or lower.

QUESTION: Is the class's complain about harsher grading justified? ( use a : 0.05 )
