Optiоnаl up tо 2 pоints of extrа credit: Shown is the meаn EMQ (Everyday Memory Questionnaire, a test designed to measure memory failure in everyday life) score out to three years comparing SARS-CoV-2 infected vs. uninfected individuals from a study of 111,992 individuals (Prospective Memory Assessment before and after Covid-19, N Engl J Med 2024; 390:863-865). Figure 1. Mean scores on EMQ comparing SARS-CoV-2 infected vs. uninfected individuals; higher scores indicate worse memory problems. Copyright 2024 by Dr. Jonathan A. Miller. All rights reserved.

What does this graph suggest about infection with SARS-CoV-2? Please explain. Include information and descriptions from the graph to support your explanation. 2. Comparing the trendlines on the left side of the graph to the right side of the graph, what does the trend toward the right side of the graph suggest? Please hypothesize; be sure to include an explanation with supporting information. 3. Comment briefly on the sample size of this study - should this sample size give us confidence in this work? Why or why not? 4. Although the graph does not explain this, propose an explanation as to what the virus might be doing to people that could result in this outcome observed.
Eighty cоllege students were аsked tо rаte twо scientists, one mаle and one female, on their knowledge about their topic areas. Each student was given two passages to read: one passage was about the numerous bio-domes in the world (“Biology”) and another passage was about enhancing the education of elementary school children (“Education”).Half of the students were told that the Biology passage was written by a female and the Education passage was written by a male. The other half of students were told the Biology passage was written by a male and the Education passage was written by a female. Then students rated the scientist’s knowledge on their topic areas on a scale ranging from 1 (“Does not display a professional level of knowledge”) to 100 (“Displays a thorough knowledge of the topic”).A two-factor ANOVA was conducted, and the mean ratings are listed below for each scientist gender and topic area condition. Assume that any effects (or mean differences) you measure are statistically significant. Scientist Gender Female Male Topic Area Biology 50 65 Education 80 70 a) State whether the results show main effects and/or an interaction. b) Significant or not, clearly describe each of these effects and the interaction in Plain English. I am expecting you to interpret the patterns not an omnibus interpretation.
