Fall, 2017 terms. For all problems show your work, and state your conclusions in non-statistical I. The following data are from a study of the number of sexist words in male group conversations after having been either given or not given gender sensitivity training. Groups Without Training Groups With Training 10 a. State the null hypothesis and the alternative hypothesis. b. Calculate t and compare it with the t critical at the .05 level. What are your conclusions? Report on the effect size using eta-squared. Construct a confidence interval for the true mean difference. 2. A study was done looking at the number of pounds participants lost after six months of a weight loss program. Program A was diet only, Program B was diet and exercise, and Program C was exercise only. The dependent variable was the number of pounds lost.Explanation / Answer
Answers-
a. Null Hypothesis- There will be no significnat difference in the number of sexist words used by males during conversation.
Alternate Hypothesis- Males who undergo gender senstivity training will use less sexist words than those who do not undergo any training.
b. The obtained means and standard deviations (SD)of the two groups are-
Groups without training- 9.40 and SD= 1.14
Groups with training- 5.00 and SD= 1.87
The obtained t value is 4.49; df= 8; p<.05 level of significance. This indicates that there are significant difference in the number of sexist words used by males who undergo training than those who do not undergo training. In this case, males who underwent gender senstivity training definitely use lesser sexist words in their conversation.
