Question 1 (Unit 10) 24 marks This question concerns the analysis of the mustard seedlings eaperiment that you were asked to carry out in Unit 10. You will need to use Minitab to answer ports {6) and (e). (a) In one or two sentences, describe how your experiment went; for example, mention any difculties that you faced along the way. Then present a table of your results, similar in layout to Table 3 of Unit 10 (Subsection 3.4). Indicate clearly the units in which you made your measurements (for example, millimetres) and the measurements that correspond to seedlings whose stems were cut during their growth- Then proceed to part (b) of the question. If, however, you were unable to collect data of your own, then state this and explain why. Instead of presenting results in a table, draw stemplots for each of the two samples of data given in Table 1, including only measurements from seedlings whose stems were cut during growth. Also, give the main reason for producing such stemplots in the context of a t-test, and comment on the shape of the stemplots relative to this reason. Table 1 Lengths of roots (in mm) obtained in a mustard seedlings experiment Seedlings grown in light Seedlings grown in dark 24 30 21 29 18 27 x 18 x x 42 x 22 17 27 24 x 29 31 31 x 32 x 28 24 26 32 27 40 23 22 25 x 32 x 29 35 25 x 41 In Table 1, measurements given in bold were obtained from seedlings whose stems were cut during their growth. A cross indicates a seed which did not germinate. [6]
