The fundamental axiom of preventive medicine suggests that: Select one: a. We should screen the population to identify those with only slightly abnormal values (e.g. blood pressure) and then treat those individuals preventatively. O O b. We should screen the population to identify those with highly abnormal values (e.g. blood pressure) and then treat only those individuals. C. We should screen the population to identify those with only slightly abnormal values (e.g. blood pressure) and then only treat those individuals who show symptoms of disease. d. We should not screen the population and identify those with highly abnormal values (e.g. blood pressure) as they become sick and then treat only those individuals.
1. An aquaponics system is a system in which fish and plants are grown together. Shane Ahrens wanted to know if tumbled glass could be used as a media in an aquaponics system. He grew kale in clay and glass (in mesh cups suspended in the water) and measured kale biomass. What is the null hypothesis? What is the alternative hypothesis? Calculate the sample mean and variance for each treatment and then calculate the t statistic and degrees of freedom. Kale Biomass (mg) Clay Glass 17.5 37.1 13.9 31.1 31.2 28.7 29.9 37.5 22.5 28.1 Mean Variance (n, – 1)s², + (n2 – 1)s²2 × n + n2 -2 + n2 d.f. = If you conduct this analysis in R, the output tells you the p-value = 0.042. What conclusion can you make (i.e., accept or reject the null hypothesis)? Explain how you reached this conclusion. Write a sentence as you would for the results section of a paper.
You wish to determine the abundance of the state- and federally-endangered Prairie Fringed Orchid (Platanthera lecuophaea) in a local prairie. (a) The prairie is approximately 100 acres of relatively flat terrain. Considering the “basic” sampling strategies, what might be a good sampling design (can just give the name)? Why? (b) You decide also to evaluate the abundance of the orchid in another prairie. The second prairie is of similar size but has a hilly terrain. What might be a good sampling strategy? Why?
1. If quantitative change were all that existed, what would a butterfly be? What would a human being be? First, think about how a butterfly and a human start out; then think of how that being would end up if only quantitative change existed. Try your best on this question. Remember that the professor provides the expected answer. Do not copy an answer from students in previous semesters as this practice prevents true understanding of concepts.

Group of answer choices a)The hypothesis that any patterns in the observed data is due to chance alone and therefore significant. b)The hypothesis that the observed data is invalid c)The hypothesis that any patterns in the observed data is due to chance alone and therefore not significant. A scientist usually accepts a p-value (or alpha level) of 0.05 as the threshold value to reject the null hypothesis. Group of answer choices a)True b)False
