5. Eighteen plants of the same age and genetic strain were randomly divided into three groups, each containing 6 plants. One group was left untreated, one was infected with virus A, and one was infected with virus B. After one week, the activity of a particular enzyme (in pl 02/ mg protein/ min) was measured in cach plant. The experiment was conducted to investigate whether infection by either virus affects the activity of this enzyme. The following data were obtained: Control Virus A Virus B 1.47 2.44 2.87 1.62 2.31 3.05 1.06 1.98 2.36 0.89 2.76 3.21 1.67 2.39 3.00 1.21 2.54 3.10 State the response variable, the factor and the treatments under investigation, experimental units and number of replicates per treatment. [4] Use the exploratory data analysis provided in the MINITAB output to indicate if there are trends in the data to support the research hypothesis. [4] At a 5% level of significance test for a difference in mean enzyme activity among treatments. Use the appropriate MINITAB output to report the results of this test. Provide full details including hypotheses, test statistic and p-value, test decision and conclusion. [7] (iv) State the assumptions of the hypothesis test used under (ili) and investigate whether these assumptions are satisfied. Use the MINITAB output as appropriate, give the name of the tests, provide the test statistic and p-values, interpret any graphical output and formulate the conclusion. [5] (v) Use MINITAB output to investigate which treatment has produced a difference, include the name of the test, the measures reported and any relevant results with interpretation.
