The following 14 questions (Q18 to Q31) are based on the following example: A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (1 = 1050). The 16 students who attend the preparation course average 1150 on the SAT, with a sample standard deviation of 300. On the basis of these data, can the researcher conclude that the preparation course has a significant difference on SAT scores? Set alpha equal to .05. Q22: Set up the criteria for making a decision. That is, find the critical value using an alpha = .05. (Make sure you are sign specific: + ; - ; or + ) (Use your tables) Summarize the data into the appropriate test statistic. Steps: Q23: What is the numeric value of your standard error? Q24: What is the z-value or t-value you obtained (your test statistic)? Q29: What is the new critical value you will use for this calculation? Q30: As you know, two values will be required to complete the following equation: sus
