whole blood platelet fresh plasma PROBLEM: The goal of a study in 2005 by Potteiger et al. was to evaluate the effects of dextrose 1 11 10 13 different blood components on hemoglobin level when combined with dextrose 2 12 10 15 dextrose 3 11 15 concentrations of dextrose. On the right are the results of the increase in units of dextrose 4 12 15 hemoglobin levels from a sample of recipients after given specific blood units. Test dextrose 5 10 12 8 the claim that there is a difference among the means at 99% confidence level. Use the p-value method of hypothesis testing. STATISTICAL OUTPUT / RESULT: QUESTIONS (1 point each number): 1. Identify the independent variables. 2. Identify the dependent variable. 3. Identify the tail of the test 4. Give the null hypothesis in words. 5. Give the alternative hypothesis in words. 6. Determine the critical value or p-value (). 7. Identify what test to be used. 8. Explain why this test is most appropriate. 9. Make the decision using specific evidence. 10. Summarize the results for the study.Person Computer Games Exam Grade PROBLEM: A 12 81 A group of BSMLS sophomores wanted to determine if the amount of computer B 16 84 C 20 87 games a person plays can lead to reduction of grades. They observed 7 people D 14 82 over the span of 2 months and noted down the number of times they played E 17 86 computer games and the grade they got on their final exam. The results are on the 14 84 right. Determine if playing computer games is associated with exam grade. G 12 82 QUESTIONS (1 point each number): STATISTICAL OUTPUT / RESULT: 1. Give the null hypothesis in symbols 2. Give the alternative hypothesis in symbols. 3. Identify the tail of the test. 4. Give the null hypothesis in words. 5. Give the alternative hypothesis in words. 6. Identify what statistical test to use. 7. Explain why this test is most appropriate. 8. Interpretation of the relationship. 9. Summarize the results. 10.

They observed 7 people over the span of 20 84 2 months and noted down the number of times they played computer games and the 21 83 n m On grade they got on their final exam. The results are on the right. Determine if playing 10 78 computer games is associated with exam grade. With alpha = 0.01, use the p-value 28 method to identify if the association is significant.
