- From the study on work sampling, it was found that a group of machines - consisting of 4 machines - were operated by operators, it was noted that 65% of machines could be operated without the need for operators to attend and 35% of operators would be present to carry out loading / unloading, maintenance activities , and / or other machine service activities. Furthermore, what is the estimated machine hours that will be lost per 8 hours of work due to "scarcity" of operators?An agronomist is interested in comparing the efficacy of two fumigants (A and B) and a control (O) in eliminating wireworms. A field is divided into 4 sections, each section containing 3 plots. Fumigant A, B and O were randomly assigned to one plot within each section. The number of wireworms that remained on each plot after application of fumigant was recorded. Give a possible RCBD layout for the experiment.In order to ensure the quality for a processing line, five sample were taken from the production run and measured.

- As horses get older, poor hoof and tendon health leads to joint pain, reducing a horse’s activity level. Such a reduction can lead to other health concerns such as obesity and a decrease in energy due to lack of exercise. A study is to be conducted to determine which of two diet supplements, Vitamin C and D-cycloserine, is more effective in promoting hoof and tendon health and reducing the onset of osteoporosis in horses. Researchers will randomly select a total of 300 horses from ten different large animal veterinary practices around the country. All of the horses are more than 5 years old, and their owners have given consent to participate in the study. Changes in hoof and tendon health will be evaluated after 6 months of treatment. What would be an advantage to adding a control group in the design of this study? Assuming a control group is added to the other two groups in the study, explain how you would assign the 300 horses to these three groups for a completely randomized…Also construct a Pareto chartThe government of Ghana has decided to automate the analysis of judged cases to flag out poorly judged cases and to determine whether the cases processed at the law court were fairly attended to or not. At artificial intelligent software using Bayesian filter is to be used to measure the intelligence in processing legal cases to determine whether a judgement made by judges are fair or not. A set of cases were fed into the memory of the software for processing the cases and determine fairness in the cases. The filter is to determine following probabilities: P(J)= probability that there was a judgement on the case and the judgement was fair. P(J’) probability that there was a judgement on the case and the judgement was not fair. P(E) Probability that there were evidences and the evidences were valid. P(E’) Probability that there were evidences and the evidences were not valid. Let P(J) = 0.85 be probability that there was a judgement on the case and the judgement was fair. Let P(E/J) =…

- An experiment was conducted to compare the effectiveness of four training programs, namely, A, B, C, and D in training assemblers of a piece of electronic equipment. Twenty employees were randomly selected and assigned to each program, that is, five employees per program. After completion of the training courses, each person was required to assemble four pieces of equipment, and the length of time (in secs) to complete the assembly was recorded. The summary of the data gathered is recorded in the table. At α=0.10, test for the hypothesis that the assembly times for people trained are the same for the four programs.
