You will provide your answer as a Word document into which you will have pasted your graphs and analyses from Prism.

The questions we want to answer are:

1. Are males significantly taller than females in our class?

2. What correlates with height in our class?

3. Do people eating more vegetables report their health as better?

Question 1: Are males significantly taller than females in our class?

i) Make a correctly labelled graph of the data showing the means and appropriate error bars as well as individual values. (4 marks)

ii) Carry out the appropriate analysis to test whether the mean male height is significantly different from the mean female height.

iii) Report exactly what test you used and why, as well as the p value and explain what it means in this case. (2 marks) If I gave you the heights of students in another 30 classes at Flinders, how would you test whether your class was unusually small or tall? Why would you use this approach? (2 marks)

Question 2: What correlates with height in our class?

i) Carry out the appropriate analysis to test whether Height correlates with Resting Pulse Rate in our class. What do you conclude? (2 marks)

ii) How much of the variation in resting pulse rate in our class is explained by the variation in Height? Show the appropriate graph to illustrate this (2 marks)

iii) Carry out the same analysis with other variables to find one that DOES and one that DOES NOT significantly correlate with height in our class. Show the linear regressions and analysis to justify your conclusions. (3 marks)

Question 3: Do people eating more vegetables report their health as better?

Carry out the appropriate analysis to test whether people eating more vegetables (>2.5 serves/day) report their health as better (good or above). Show the data, and the analysis and give the appropriate interpretation of the result. (5 marks)
