l 4. Past studies showed that maternal diabetes results in obesity. blood pressure, and glucose tolerance complications in offspring. The fiie A4_Bio0dPressure_Diabete_Q6.xlsx contains the arterial blood pressures, in millimetres of mercury [mm Hg]. fora random sample of 16 children of diabetic mothers, the same data that was presented in Question 6. of Part A. The sample mean is f = 85.99 mm Hg and the sample standard deviation is s = 8.08 mm Hg. (0) Use the proper graphical toois in R and R commander to assess whether it is reasonable to apply the onesample tinterval and onesample ttest procedures. Give the relevant R output. Make sure to write down the assumptions of the procedure and address whether the assumptions are satisfied. (5 marks] (b)Question 6 (a) in Part A asks you to test at the 1% signicance level whether the mean arterial blood pressure of all children of diabetic mothers Whig. Obtain and give the appropriate R output that veries your answer in Part A. (2 marks) (c) Test at the 2% significance level whether the mean arterial blood pressure of all chiidren of diabetic mothers is different from 85 mm Hg. Include all the six components of a hypothesis test in your sotution. Include the relevant R output. (6 marks] (d)Obtain a 98% twosided confidence interval for the mean arterial biood pressure of all children of diabetic mothers. Give the relevant R output. [2 marks) (e) Does the interval in part (d) support the result in part (c)? That is, does the interva! in part (C!) also give evidence that the mean blood pressure of all children with diabetic mothers is different from 85 mm Hg? Explain your answer. (3 marks]
