The data provided in the table below comes from a study in which a researcher wanted to determine if the emotion elicited by different pictures would significantly impact the number of images remembered. The researcher randomly assigned subjects into one of three different groups. One group viewed a series of negative images, another group viewed a series of neutral images and the final group viewed a series of positive images. Did the emotion of the image make a significant difference in the number of images recalled? The data you will need to test the hypothesis are in the tablebelow: Negative Image Group Neutral Image Group Positive Image Group Recall Score Deviation Squared Dev Recall Score Deviation Squared Dev Recall Score Deviation Squared Dev 19 10 14 24 6 11 25 3 18 15 8 9 20 2 12 Test the hypothesis for the problem above, following these steps: a) write the null and alternative hypotheses;b) set alpha at .05 and determine the critical value(s); c) use the correct formulas to compute the relevant values and the test statistic and enter these values in the table below

Question

The data provided in the table below comes from a study in which a researcher wanted to determine if the emotion elicited by different pictures would significantly impact the number of images remembered. The researcher randomly assigned subjects into one of three different groups. One group viewed a series of negative images, another group viewed a series of neutral images and the final group viewed a series of positive images. Did the emotion of the image make a significant difference in the number of images recalled? The data you will need to test the hypothesis are in the tablebelow:

Negative Image Group	Neutral Image Group	Positive Image Group
Recall Score	Deviation	Squared Dev	Recall Score	Deviation	Squared Dev	Recall Score	Deviation	Squared Dev
19			10			14
24			6			11
25			3			18
15			8			9
20			2			12

Test the hypothesis for the problem above, following these steps: a) write the null and alternative hypotheses;b) set alpha at .05 and determine the critical value(s); c) use the correct formulas to compute the relevant values and the test statistic and enter these values in the table below d) state the statistical decision; e) state a brief conclusion.
