- Homework Statement
- The teachers claim that at least 20% of the students arrive late for class. The students say it is no more than 10%.
What is the null hypothesis (H_0) and alternative hypothesis (H_1) from the perspective of a) the teachers; b) the students?
- Relevant Equations
- none
This is a homework question in my daughter’s maths class. When I did stats I always had examples where there were two variables : an example being swallow wingspan and sex. The statement that males have larger wingspan would therefore be the H_1 and the H_0 would be that there is no impact of sex on wingspan.
In this example, I argue that the teachers’ claim is H_1 and the H_0 is that the data will not support that claim. My daughter says that the claim should be the status quo (H_0) and the H_1 is the alternative hypothesis that it’s not p greater than or equal to 0.2
Which of us is wrong?
Thanks!
