7-2) The following table shows the bail bond (in US dollars) a sample of arrested men and women had to pay to get out of jail.

men	women
1000	500
300	250
1500	250
200	200
500	500
150	250
1000	100
500	150
1200	250

Formulate the null hypothesis stating no gender difference in the bail bond the arrestees have to pay
Formulate the alternative hypothesis
Using the independent-sample t test, test the null hypothesis [H0]
List the value of the critical t you used to test H0 [df = n1 + n2 – 2; p = .05; 2-tail test]
Reach a statistical conclusion using p = .05, 2-tail test, and the appropriate degrees of freedom
Interpret your results
