Question 1
Bob loves watching ASMR videos and is curious about the effects that it has on those who watch them. Upon further reading, he found that people often reported a general sense of calmness after watching ASMR videos. Research suggests that the calmness experienced could be a result of physiological changes (e.g. lowered heart rate). Thus, Bob sets out to study whether participants will have lower heart rate levels after watching ASMR videos compared to neutral or sports videos. One hundred eight participants were instructed to watch 3 different types of videos in randomized order. The participants' heart rates were recorded throughout each video and averaged by each video duration. Thus, the greater the average heart rate reading, the higher the heart rate level after watching a specific video type.
Name of variables/levels:
- IV: Type of video (ASMR, neutral, sports)
- DV: Heart rate level
Scale of measurement:
- IV levels: Nominal
- DV: Continuous
What statistical test should Bob run?
Bob should run a one-way analysis of variance (ANOVA) to compare the mean heart rate levels across the three different types of videos.
Suggest one null hypothesis:
There is no significant difference in heart rate levels among participants after watching ASMR, neutral, and sports videos.
Suggest one alternative hypothesis:
There is a significant difference in heart rate levels among participants after watching ASMR, neutral, and sports videos.Question 2
Mitosis - cell division - is why injuries to the nervous system - brain, spinal cord, or nerves - can cause lifelong loss of function.
3. What cell organelle is missing in neurons after 2 years of life that prevents them from dividing by mitosis? Type answer as a lowercase word. (1 point)
Students often encounter toxins when working in the lab. These toxins can be absorbed through the skin. The cells of the liver are very effective at breaking down these toxins so they will not damage the body.
4. What cell organelle would be in high abundance in these liver cells to allow effective breakdown of toxins? Type answer as a lowercase word. (1 point)
