Question

Problem Set 2: A product developer wanted to know the preferred advertising strategy for a new toothpaste, and if it differs among three target demographic groups: 12-24, 25-40, and 40-60 year olds. There were two versions of advertisements for the toothpaste. Each person indicated their favorite version of the advertisement, as indicated in the table below. Did the preferred advertisement version differ by age group? (Note –conclusions may not be a good reflection of the data due to the small sample size – this example is purely for educational purposes)

		Advertisement version		TOTALS
		A	B
Age group	Young	3	7	10
	Mid	4	6	10
	Older	6	4	10
	TOTALS			30

1.) Write an APA-style Results section based on your analysis, include the statistical statement within a complete sentence that mentions the type of test conducted, whether the test was or was not significant, and if relevant, effect size and/or post hoc analyses. Lastly, do you reject or fail to reject the null hypothesis.

Chi-Square Tests Asymptotic Significance Value df (2-sided) Pearson Chi-Square 1.900 2 .387 Likelihood Ratio 1.916 2 384 N of Valid Cases 30 a. 3 cells (50.0%) have expected countless than 5. The minimum expected count is 4.33. The hypothesis being tested is: Ho: The preferred advertisement version does not differ by age group Ha: The preferred advertisement version differ by age group The p-value from the output is 0.387. Since the p-value (0.387) is greater than the significance level (0.05), we cannot reject the null hypothesis. Therefore, we cannot conclude that the preferred advertisement version differs by age group.
