Question

Researchers studied nausea among a sample of hospitalized patients. They used a t-test to compare average nausea scores in men and women. They report men had an average score of 1.02 and woman had an average score of 1.79. (p<0.001) Which statement is correct?

Men had significantly less nausea

Men had 79% less nausea but we can not determine if this is a significant relationship.

A paired t-test was appropriate because the patients were all from the same hospital.

There is a significant positive correlation between nausea and gender.

Answer 1

it is given that the p value is less than 0.001, which means that the result is significant. Therefore, we can say that the mean difference is significant at 0.05 significance level

option A is correct because the p value is less than 0.001

option B is incorrect because we have enough data information to determine the significant relationship

option C is incorrect paired t test is incorrect as the male and female data sets are independent

option D is incorrect because there is no information regarding the correlation
