The correct answer is that the case fatality rate of the Pacific Pox must be high.
A case fatality rate is the ratio of deaths due to a certain disease (throughout the duration of the disease in question). In this scenario, since there are no survivors left, the proportion of deaths among the people who had this disease is obviously rather high.
Group of answer choices as it was omitted
a. matching
b. randomizing
c. counterbalancing
d. analysis of co-variance
Answer: Randomizing
Explanation:Randomizing, a statistical theory in the design of experiment generally used in randomized controlled trials of experimental research is defined as a method which involves randomly assigning experimental units to any treatment group which is based on chance and not choice. Randomization reduces or eliminate bias and controls extraneous variables (an unnecessary variable which is not the Independent Variable that can influence the dependent variable) that could affect results giving a more reliable results.
Answer:
D). They have not defined happiness or how it will be measured.
Explanation:
As per the question, the most consequential flaw or error in this study design is that 'Jean-Gabriel and Magali have not defined happiness and neither provided a description or method that describes how it will be measured.' This flaw would make the design ineffective as it would not be able to produce reasonable deductions or conclusions because they have decided that 'they would visit a mall to survey people of different ages' but this requires a scale on which they would measure happiness. <u>Since they have not mentioned any such scale which implies that they won't be able to collect data and hence, the study could not be taken forward.</u> Therefore, <u>option D</u> <u>displays the major error of this design that makes it invalid</u>.
