Question 1. [ 9 marks ] [Chapter 7] I psychologist was interested in whether attitudes toward death differ between organ donors (people who, on their driver licence, indicate that they are willing to donate their organs) and non-organ donors. 25 organ donors and 69 non-organ donors were randomly selected and the extent to which each person was concerned about issues relating to death was measured using the Templar Death Anxiety Scale (DAS). The DAS produces scores ranging between 0 and 15 with higher scores indicating greater anxiety towards death. Summary statistics are displayed in the table below: m (a) Carry out a Itest to investigate Whether there is a difference between the underlying mean DAS score for all organ donors and that for all non-organ donors. [8 marks] Notes: (i) You must clearly show that you have followed the \"Step-by-Step Guide to Performing a Hypothesis Test by Han \" given in the Lecture Workbook, Page 12, Chapter 7. (ii) At Steps 5 and 8, it is necessary to use the tprocedures tool on Canvas (Assignments > Assignment 3) to determine the standard error and the tmultiplier. (iii) At Step 6, it is necessary to use the t-procedures tool on Canvas to determine the Pvalue. (iv) Refer to the instructions on Page 1 of this assignment: \"Hypothesis tests in this assignment". (b) Does the condence interval given in part (a) contain the true value of the parameter? Briey explain. [ 1 mark]
