Textbook Question
Chapter 12.1, Problem 11E
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.
The authors of the paper used a chi-squared goodness-of-fit test to test the null hypothesis H0: p1 = 0.50, p2 = 0.50, where p1 is the proportion who would respond Monday and p2 is the proportion who would respond Friday. They reported X2 = 11.00 and P-value < 0.001. What conclusion can be drawn from this test?

This depends on the GPA the student gets and having his/her application submitted on time. 40.1% of the students applying have the required GPA. Given that the student has the required GPA, 77.56% of the students received a scholarship. And given that the student doesn't have the required GPA, 6.51% of them received a scholarship. Knowing that a student got a scholarship and have the required GPA, 96.46% of them had applied before the due date. On the other hand, the probability that the student submitted his application on time knowing that he didn't have the required GPA and he didn't get a scholarship was 1.79%. Given that the student didn't get a scholarship and had the required GPA, 2.22% of the applications were submitted on time. Of all applications, 3.4% of the applications were submitted on time, the student didn't have the required GPA and the student got a scholarship.arrow_forward3) At the end of some semester a certain student received the grade report shown below.

In the study, the researchers visited the children's homes between the ages of 14 and 30 months and recorded the amount of "number talk" they heard from the children's parents. The researchers then tested the children's knowledge of the meaning of numbers at 46 months. The following data are similar to the results obtained in the study.
