Unit 3 Minitab Question 1: A study conducted at the local elementary school wants to see if providing lunch will increase test scores. The previous year's average test score is 65. Before fully implementing this expensive proposal, a random sample of 10 students were given hot breakfasts for a week and then given the same standardized test. Test Scores 65 75 58 80 95 60 88 85 70 73 a. State the null hypothesis and the alternative hypothesis in words. b. State the null and experimental hypotheses in symbols. c. Why is this a good use of the 1-sample t-test? d. Identify the Independent Variable (IV) and Dependent Variable (DV). e. Conduct the statistical analysis using Minitab. f. Conclusions? Reject or fail to reject the null? g. Explain the confidence interval and the direction of the effect. h. Check the assumption of normality
