. 4. Are women more suggestible than men? You compare men and women’s suggestibility mean scores (measured at interval scale)

8. How many traffic tickets do men under 25 get, compared to women under 25? Data are collected on 18-25 year old men and women.

Answer 1

1] Data are Paired here so paired t TEST will be used. (Before and after)

2] Since population standard deviation is known therefore we will use Z test for one population mean.

3] Since population standard deviation is unknown therefore one sample t test will be used.

4] Men and Women are independent samples so independent sample of t test will be used.

5] Chi square test of independence will be used because we are testing association between gun control opinion and parties.

6] Three groups are independent so One Way Anova.

7] Correlation t test will be used to find is there any correlation between the two variables.

NOTE: please Repost question 8 with data.
