**Psyc 10 Laboratory Assignment 4 – Chapters 7 & 8****Instructions:**Ensure you receive your stamp prior to closing out data, syntax, or output windows.**SPSS Application #2**A psychologist is interested in whether a standard anxiety-reduction program (arp) will be effective for altering test anxiety. The psychologist recruited ten students to participate in a six-week program designed to alter anxiety. The psychologist measured the students' anxiety before and after the program. The students’ scores on the two administrations of the anxiety inventory are presented in the table below:| Student ID | Before Anxiety Program (arppre) | After Anxiety Prog (arppost) ||------------|--------------------------------|------------------------------|| A | 48 | 40 || B | 46 | 38 || C | 44 | 42 || D | 48 | 41 || E | 43 | 43 || F | 47 | 43 || G | 47 | 41 || H | 45 | 44 || I | 44 | 43 || J | 45 | 40 |1. **Identify the type of t-test:**2. **Identify the independent variable:**3. **Identify the dependent variable:**4. **State the Research hypothesis and Null hypothesis (Step 1 of hypothesis testing):** - **H1=** - **H0=**5. **State your null decision and conclusion (Step 5 of hypothesis testing) for each of the following levels of significance:** - **.05 level – null decision:** Conclusion: - **.01 level – null decision:** Conclusion:6. **Report the statistical sentence (APA format) for the alpha significance of:** - **.05 level:** ____________________________________________ - **.01 level:** ____________________________________________---(Note: For clarity, students need to fill in the blanks for hypothesis, null decisions, and statistical sentences based on their analysis of the data.)
