Directions:

For SPSS output, please paste the appropriate tables in the Word document and make reference to each table and why you are including it. If a table is associated with one of the hypothesis testing steps, it must be clear which step and why you are including it there. Please also discuss and interpret as appropriate. Paste SPSS tables in each problem where appropriate. (Please paste the table within the problem rather than append at the end of this document).

1. A researcher sampled 100 women from a medical record database and identified their smoking status and parity. Use the 5 steps of hypothesis testing to determine whether pregnancy and smoking status are independent.

   Smoking Status	Parity
   Before Pregnancy	No children	Children
   Nonsmoker	20	20
   Smoker	5	55

2. A medical student surveys adults to determine if gender and seat belt use are independent. Use the 5 steps of hypothesis testing to determine whether gender and seat belt use are independent.

   Seat belt use	Gender M	F
   Belt	70	60
   No belt	30	40

3. A researcher collected daily sodium intake and systolic blood pressure readings on 12 patients. Obtain the regression equation from SPSS and include the table you used for the data. Use the 5 step hypothesis testing approach to determine if the regression equation is significant at alpha = 0.05. What would be a likely blood pressure for a person with a sodium intake of 6.3: 7.6?

   Sodium	SBP
   6.8	154
   7	167
   6.9	162
   7.2	175
   7.3	190
   7	158
   7	166
   7.5	195
   7.3	189
   7.1	186
   6.5	148
   6.4	140

4. Two health inspectors rate 11 hospitals on cleanliness. Determine whether their rankings are comparable, using the appropriate nonparametric test and the 5 steps of hypothesis testing.

   Inspector 1	Inspector 2
   2 3 2 3 1 4 5 3 1 3 4	1 3 3 2 2 5 4 2 1 4 3

5. A medical informatics manager reviews sick day use in her department. She identifies that employees in her small department used the following amount of sick time in the past year:

Men: 5,10,2,0,6,4,5,15

Women: 8,9,3,5,0,4,15

The statistician indicated she should use a nonparametric test to determine if there is a difference in sick time use between the men and women in her department. Use the 5-step approach to hypothesis testing and alpha=0.05 to determine if there is a difference.
