Lilo wants to know if equal proportions of students in her class know how to surf well, know how to surf a little or do not know how to surf. She randomly samples 60 students in her class and asks them if they know how to surf. Twenty students indicate that they do not know how to surf 'don't know', while 30 students indicate they know how to surf well 'know well,' and 10 students indicate they know how to surf ‘a little’. State the hypothesis being tested by Lilo (H0 and HA)? Test Lilo's hypothesis at α of .05. Enter the test statistic, critical value, and decision as part of your answer. Test statistic = Critical value = Do you reject or retain the null hypothesis that the slope is not different from zero? (Enter "Reject" or "Retain"):
