Question

IQ, or intelligence quotient, is one way to measure a person’s ability to reason and
problem solve. The IQ population standard deviation 15 points. A statistics teacher claims
that students in his classes have an IQ greater than 100. He samples 20 students, and the
IQ scores are listed below:
86; 90; 110; 115; 100; 95; 91; 103; 98; 87;
105; 95; 103; 114; 102; 99; 120; 120; 93; 101
505
At the α = 0.05 level, is there evidence to support the teacher’s claim?
