Question 5Twenty patients sampled at random were matched by ageand BMI. One of each pair was assigned at random to a new treatment and the other toan existing treatment. Ultrasound examination of a certain tumour weight (in grams)produced the following results.Existing Treatment 15.5 5 8.5 10.6 12.5 6.5 8.4 10.5 8 10New Treatment14 5.7 9 11.5 107.5 8 9.9 10.57To answer the following questions, report the numerical computations to four decimalplaces.(a) Test whether there is a difference in the two treatments at 5% level of significances.(b) Find a 90% confidence interval for the mean difference in the treatments.(c) What would be the conclusion in (a) if we had wrongly ignored the pairing?
