Temperature has a direct correlation with aggression. Knowing this, a researcher predicts that participants completing a frustrating task will express more aggression when they are in a 90-degree room than a 70-degree room. The researcher finds t(20) = 2.33, p < .05. Knowing this, what should his research conclusion be? A. That people were equally aggressive in the 70-degree room and 90-degree room. B. That people were more aggressive in the 90-degree room than the 70-degree room. C. Unfortunately, there is not enough information to make a full conclusion. D. That people were more aggressive in the 70-degree room than the 90-degree room.
A professor wanted to study whether there was an association between a person's age and their likelihood to use social media. He surveyed members of Gen Z, Millennials, and Gen X. Below you will find the data that was collected: YES, use social media NO, do not use social media H₂: a=0.05 DF=_ Gen Z 78 11 a. Perform a Chi-Square Test for Association to see if there is evidence to show there is an association between age and likelihood to use social media? Ho: Conclusion: b. Fill in the blanks using your table: X²= Circle one: Millennials 124 19 Number of Gen Z that use social media= Total number of Gen Z surveyed = Gen X 79 24 P-value= Fail to Reject H. OR Reject Ho c.

Health care workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. Each in a sample of 44 hospital employees who were diagnosed with a latex allergy based on a skin-prick test reported on their exposure to latex gloves. Summary statistics for the number of latex gloves used per week are x= 19.4 and s = 11.7. Complete parts (a) - (d). a. Give a point estimate for the average number of latex gloves used per week by all health care workers with a latex allergy. b. Form a 95% confidence interval for the average number of latex gloves used per week by all health care workers with a latex allergy. (Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) c. Give a practical interpretation of the interval, part (b). O A. One can be 95% confident that latex gloves cause allergies for all who use a number of gloves contained in the interval. O B. One can be 95% confident that the…
