Researchers from the university of Kent, UK, were interested in whether collectivist or individualist attitudes are related to one’s intent to comply with social distancing and safety guidelines during COVID-19. Participants were classified as either collectivist or individualist, and rated their intent to comply with guidelines on a scale from 1-5, where 1 is definitely not and 5 is definitely yes. Please conduct an independent-groups t test to determine if there is a significant difference in intention to comply between individualists and collectivists.

In addition, please:
- report cohen’s d
- report r^2
- conduct and interpret an F-MAX test
- include 95% confidence intervals
- report your answer in words that directly address the research question

For collective group; the data is as

3 2 6 4.5
4 6 24 4.5
5 12 60 4.5

For individual, the data is as

Finally, the researchers are interested in whether workplace cohesion attitudes change, as employees move from sub-optimal working conditions to above average working conditions. They collect data from the same employees, first when working under sub-optimal conditions and then one month after moving to above average conditions. Test for this hypothesis based on the new data below.                                                 Sub-standard   Above average       Difference (sub-above) x    80.00 76.00 4.00                      s 6.00 8.00 3.00                      n   40.00 36.00 36.00 Type of...

Researchers at the University of South Alabama compared the attitudes of male college students towards their fathers with their attitudes toward their mother. Each of a sample of 13 males was asked to give a numerical grade to describe his relationship with his father and a numerical grade to describe his relationship with his mother, with 1 being the lowest and 5 being the highest. The result is reported as follows: Father Mother Difference Mean 3.85 4.15 -0.31 Sx 1.07...

researchers at Vanderbilt University were curious about whether consumers are able to use the information on nutritional labels. They surveyed 200 primary care patients at the University Medical Center. In one question, respondents were asked to calculate the number of grams of carbohydrates in a single serving of soda, using the information on the label of a 20-ounce bottle (2.5 servings). Only 32% answered correctly. With 95% confidence, what is the margin of error in this estimate? ______ If the...
