12.7 How would you answer the following question:

Next Wednesday’s meeting has been moved forward two days. What day is the meeting now that it has been rescheduled?

This question is ambiguous as “moved forward” can be interpreted in two different ways. Did you answer Monday or Friday? The authors of the paper “Even Abstract Motion Influences the Understanding of Time”

(Metaphor and Symbol [2011]: 260–271) wondered if the answers Monday and Friday would be provided an equal proportion of the time. A sample of students at Stanford University were asked this question, and the responses are summarized in the following table.

Response Frequency Monday 11 Friday 33 The authors of the paper used a chi-squared goodnessof-

fit test to test the null hypothesis H0 : p1 5 0.50, p2 5 0.50, where p1 is the proportion who would respond Monday and p2 is the proportion who would respond Friday. They reported X2 5 11.00 and P-value

, 0.001. What conclusion can be drawn from this test?
