You take a survey that is supposed  to measure whether you are an extrovert or not. The score you get on the extrovert survey is a z-score of 2.0. What does that mean about your level of extraversion compared to the average score?

What is H0? And why do we evaluate it instead of the scientific hypothesis?

You want to determine if city of residence impacts salary due to the COVID-19 epidemic. You recruit 50 subjects each from St. Louis, Memphis, and New Orleans and record their salary in January and July of 2020. To determine the location, time (January vs. July) and combined . Assume all assumptions effects on salary, you would use a are met for a parametric test. Factorial ANOVA One-way repeated measures ANOVA Factorial repeated measures ANOVA One-way ANOVA

A blog noted that​ "there has been increasing anecdotal evidence that vitamin C may still be useful as an anticancer medicine if used in high concentrations and given directly into the vein​ (intravenously)." Use this information to answer the questions below.       Question content area bottom Part 1 Explain what it means that there is​ "increasing anecdotal​ evidence" that Vitamin C may be a useful anticancer medicine.     A. There is no evidence that shows Vitamin C may be a useful anticancer medicine.   B. There is scientific evidence that Vitamin C is a​ non-useful anticancer medicine.   C. There is an increase in rigorous or scientific analysis that shows Vitamin C may be a useful anticancer medicine.   D. There is an increase in observations or personal experiences that shows Vitamin C may be a useful anticancer medicine. Part 2 How does anecdotal evidence contrast with scientific​ evidence?     A.

It is a well-known fact that 40% of college students LOVE taking Mathematics. A certain professor at WCC wanted to test to see if a majority of students at WCC LOVE taking Mathematics. To test this, the professor randomly samples 1000 students and finds that 515 of them LOVE taking Mathematics.At the 0.05 level of significance, does the above sample provide evidence to suggest a majority of students at WCC LOVE taking Mathematics? Step 1: Define the parameter & setup the testStep 2: State the Level of SignificanceStep 3: Find the value of the Test StatisticsStep 4: Find P-Value OR Find Critical ValueStep 5: State Conclusion and why

Previous studies have shown that playing video games can increase visual perception abilities on tasks presented in the gaming zone of the screen (within 5 degrees of the center). A graduate student is interested in whether playing video games increases peripheral visual perception abilities or decreases attention to peripheral regions because of focus on the gaming zone. For her study, she selects a random sample of 64 adults. The subjects complete a difficult spatial perception task to determine baseline levels of their abilities. After playing an action video game (a first-person combat simulation) for 1 hour a day over 10 days, they complete the difficult perception task for a second time. Before playing the action video game, the mean score in their accuracy on the spatial task was 0.42. After playing the action video game, the mean score was -0.08. The mean of the differences between each person's pre- and postscores was 0.5, with a standard deviation of the differences equal to…
