8.24 Body measurements, Part II. Exercise 8.13 introduces data on shoulder girth and height of a group
of individuals. The mean shoulder girth is 107.20 cm with a standard deviation of 10.37 em. The mean
height is 171.14 cm with a standard deviation of 9.41 cm. The correlation between height and shoulder girth
is 0.67.
(a) Write the equation of the regression line for predicting height.
(b) Interpret the slope and the intercept in this context.
(c) Calculate R² of the regression line for predicting height from shoulder girth, and interpret it in the
context of the application.
(d) A randomly selected student from your class has a shoulder girth of 100 cm. Predict the height of this
student using the model.
(e) The student from part (d) is 160 cm tall. Calculate the residual, and explain what this residual means.
(E) A one year old has a shoulder girth of 56 cm. Would it be appropriate to use this linear model to predict
the height of this child?

A marketing firm wishes to test the effectiveness of the audio/visual presentation of certain information as opposed to the purely audio presentation of the information. To this end 100 volunteers were given a 10 minute presentation in which the information was presented in an audio/visual format. A second group of 100 volunteers was presented the same information in a purely audio format. Each person in each of the two groups was asked the same 20 questions related to the information in the presentation. The audio/visual group had an average of 10.5 correct responses with a sample standard deviation of 4. The purely audio group had an average of 9.4 correct responses with a standard deviation of 3. The marketing firm believes this means that the audio/visual format leads to better retention of the information. We test the hypotheses H0: 1 -2=0 versus Ha: 1 -2>0 at a 2% level of significance.

ANswer as much as you can urgently!!!!please Not only from question 4-10
In 2004 it surfaced in Reader's Digest presented as having happened to a teacher at an unnamed community college. Four students walked in halfway through American history test my father was giving at the local community college. "Sorry," they said, "we had a flat tire." An understanding man, Dad said that if they could answer just one question correctly, he would give them each an "A" for the exam. The students agreed. So my father handed each one a piece of paper, placed them in four separate comers and said, "Write down which tire was flat." Kurt Smith What is the probability that these four students would give identical answers if they hadn't had a flat tire? Why?

That is the first answer I got and it was also marked as incorrect. I am not sure why. I also tried the rounded version and it didn't work.
