Use the following information to answer questions 28-32.A researcher wanted to test the effectiveness of a new professional development initiative aimed at increasing teachers’ use of technology in the classroom.At the beginning of the school year, all teachers were told that using technology to improve instruction was a major district goal.32 teachers from School A attended an intensive two-day workshop about using technology.36 teachers from School B only received informational packets and contact information for the district technology specialist.At the end of the year, both groups were assessed using a technology integration index (higher scores = better integration).Mean score, School A: 8.9Mean score, School B: 7.0Estimated standard deviation of the difference between sample means: SDdifference=1.0SD_{difference} = 1.0You are told:The test statistic for the data is: tobs=1.90t_{obs} = 1.90The critical value at α=0.05\alpha = 0.05 (df=66, tcrit=±2.000t_{crit} = \pm 2.000)

Use the following scenario to answer questions 22-24. A researcher conducted a study to compare the average fasting blood glucose levels between two groups of patients: one group receiving a new diabetes medication (Group A) and another group receiving a standard medication (Group B). The following summary statistics were reported: Group A: n=35, mean = 120 mg/dL, standard deviation = 15 mg/dL Group B: n=40, mean = 130 mg/dL, standard deviation = 18 mg/dL t-statistic = -2.45 p-value = 0.017 The researcher used a significance level of 0.05.
