INSTRUCTIONS: This assignment focuses on single sample hypothesis testing (i.e., z test, Student's single sample t test, correlation). You should review Chapter 7 (and maybe also Chapter 3) of "A Student Guide to SPSS" before trying to complete this assignment. Note that some questions cannot be answered using SPSS and will require hand calculations. If you hand-write any parts of the answers to these questions, do so clearly; marks will only be given for legible writing. Another option is to use the "Insert-Equation" function in Word. Use the SPSS file 'SPSS_Assignment_5_Data.sav' to complete the assignment. The SPSS file contains data from three CogLab experiments your class has completed (i.e., Stroop, Change Detection, False Memory). The data in the SPSS file represent a subset of participants who completed each CogLab.

Marking of lab assignments will be very strict. To avoid receiving deductions, type your answers in the spaces provided in blue. You may insert additional spaces after any question as needed. In addition, use proper symbols and notation (e.g., , , t, Cohen's d, , , z, r, ) in all your answers. Unless otherwise specified, the results of all statistical tests, including p-values, should be reported in APA style. Follow the exact guidelines in your Cuttler SPSS guide (see pages 20, 26, 41, and 114-115 ("Reporting the results") for more details). Final answers should generally be rounded to 2 decimal places. You will lose marks for each and every failure to follow these directions.

In the False Memory CogLab, you saw a list of words (e.g., "bed," "drowsy," "tired," "dream") in a study phase. During the subsequent test phase you were shown words and were asked to indicate whether the words were old (shown in the study phase) or new (not shown in the study phase). The test phase lists contained three types of words. Some were old words that were shown in the study phase (e.g., "bed"; variable cOld); others were new words that were unrelated to words that were shown in the study phase (e.g., "cup"; variable fmNew); and others were lure words that were related to words shown in the study phase but that were not presented (e.g., "sleep"; variable fmLure).Answer the following questions. [3 points]

a.Evaluate the hypothesis that there is a significant negative correlation between falsely recognizing unrelated new words and falsely recognizing related "lure" words. Use an alpha level of .05.

i.State the null and alternative hypotheses, using general scientific language.

ii.State the null and alternative hypotheses, using specific statistical language.

iii.Report the results.

iv.Based on your answer to part a-iii, state your decision with respect to H₀ and provide a conclusion.

b.Evaluate the hypothesis that there is a significant correlation between correctly identifying old words and falsely identifying related "lure" words. Use an alpha level of .05.

i.State the null and alternative hypotheses, using specific statistical language.

ii.Report the results.

iii.Based on your answer to part b-ii, state whether you should reject or retain H₀ and provide a conclusion.
