Researchers studied symptom distress and palliative care designation among a sample of 710 hospitalized patients. Controlling for age, they used a t-test to compare average distress from nausea scores in men and women. Lower scores indicated less distress from nausea. They report men had an average score of 1.02 and woman had an average score of 1.79. Which statement is correct?
men had significantly less distress from nausea.
Men had half as much distress from nausea as woman but we can not determine if this is a significant difference.
Men had less distress from nausea on average than women but we can not determine if this is a significant difference.
There is a positive correlation between distress from nausea and gender.
Answer
option A is incorrect we have no p value or t test statistic tell whether there is significance or not.
option B is incorrect because men does not have half as much distress as women because 1.02 is not half of 1.79.
option C is correct because we know that 1.02 is less than 1.79, but we cant tell anything without completing any hypothesis test for the difference between the means. There is not enough data to complete the hypothesis test
option D is incorrect because there is insufficient data to say anything about the correlation

1. We reject the null hypothesis only when: a. our sample mean is larger than the population mean. b. the p value associated with our test statistic is greater than the significance level of the test we have chosen. c. our sample mean is smaller than the population mean. d. the p value associated with our test statistic is smaller than the significance level of the test we have chosen. 2.
