Question 1 (3 parts)You are preparing some sweet potato pie for your annual Thanksgiving feast.Â The store sells sweet potatoes in packages of 6.Â From priorÂ experience you have found that the package will contain 0 spoiled sweet potatoes about 65% of the time, 1 spoiled sweet potato 25% of the time and 2Â spoiledÂ sweetÂ potatoesÂ the rest of the time.Â Conduct a simulation to estimate the number of packages of sweet potatoes you need to purchase to have three dozen (36) unspoiled sweet potatoes.Part 1 of 3:Describe in detailÂ and inÂ paragraph formÂ how you will use the random numbers provided from a random number table (in part 2) to conduct 4 trials of this simulation.Â Be sure to include all of the first four steps of a simulation.Â Steps 5 and 6 are part 2 and step 7 are part 3 of this question.1.Â Identify the component to be repeated.2.Â Explain how you will model the outcome.3.Â Explain in detail how you will simulate the trial.4.Â State clearly what the response variable is.Part 2 of 3:Using the data from our random number table below, carry out your simulation from part 1.Â For each of the 4 trials, show theÂ detailedÂ outcome (package by package) and specify your overall results (total number of packages in that trial).Â ThenÂ show workÂ for analyzing the response variable.Â This is steps 5 and 6 of a simulation:5.Â Run several trials6.Â Analyze the response variable.Part 3 of 3:stateÂ a conclusion to the simulation in context. (step 7)._____________________________________________________________________________________________________________________________________________________________________ Question 2Scientists examined the glycogen content of apes' brains at the apes' normal bedtimes and after they had been kept awake for an extra 6â€‹,12â€‹, or 24 hours. The scientists found that glycogen was 29â€‹% lower among apes that had beenâ€‹ sleep-deprived for 12 hours orâ€‹ more, and that the levels recovered during subsequent sleep. These researchers speculate that we may need to sleep in order to restore theâ€‹ brain's energy fuel.â€‹a) Identify whether the above research is an observational study or an experiment.The described research is?A. observational studyB. experimentâ€‹b) Identify the subjects studied.The subjects wereÂ a)apesB)humansC) mammals.â€‹c) Identify theâ€‹ factor(s) in theâ€‹ experiment, and the number of levels for each.How many factors are involved in thisâ€‹ experiment?Number of factors______ (wholeâ€‹ number.)In the tableâ€‹ below, name theâ€‹ factor(s) and the number of levels of each.What is the name of the factor?a)glycogenb)sleepc)sleep deprivationNumber of levels for each factor/factors? ____â€‹( wholeâ€‹ number.)d) Identify the number of treatments.This experiment used ____treatments. â€‹(wholeâ€‹ number.)â€‹e) Identify the response variable measured.The response variable is?a)sleep needed to recoverb)glycogen levelc)sleep deprivationd)mental function.â€‹f) Identify the designâ€‹ (completely randomized,â€‹ blocked, orâ€‹ matched).This experiment:a)has a matched designb)has a randomized block designc)may or may not be randomizedd)has a completely randomized designâ€‹g) Identify whether the experiment was blindâ€‹ (or double-blind).A.This experiment isâ€‹ single-blind. The evaluators were blinded.B.This experiment isâ€‹ double-blind.C.It is not known whether any blinding occurred.â€‹h) Identify the nature and scope of the conclusion regarding what the results of the experiment may or may not indicate.A.If proper randomization wasâ€‹ used, the conclusion could be thatâ€‹ sleep-deprived people will not function at full mental capacity until they get the sleep they need.B.If proper randomization wasâ€‹ used, the conclusion could be thatâ€‹ sleep-deprivedÂ apesapes have significantly lower glycogen levels and may need sleep to restore that brain energy fuel.C.If proper randomization wasâ€‹ used, the conclusion could be thatâ€‹ sleep-deprived people have lower glycogen levels and that sleep restores that brain energy fuel.D.Without properâ€‹ randomization, no conclusion can be made from this experiment.d) Identify the number of treatments.
