Transcribed Image Text:You may need to use the appropriate appendix table or technology to answer this question. Ten individuals participated in a taste test involving two brands of a product. Sample results show 7 preferred brand A, 1 preferred brand B, and 2 were unable to state a preference. With a = 0.05, test for a significant difference in the preferences for the two brands. State the null and alternative hypotheses. (Let p = the probability of a preference for brand A.) ⒸH₂: P = 0.50 H₂: P = 0.50 OH: P ≤ 0.50 H₂: p > 0.50 O Ho: p > 0.50 H₂: P = 0.50 O Ho: P = 0.50 H₂: P = 0.50 O Ho: p≥ 0.50 H₂: P < 0.50 Find the number of plus signs. 7 ✓ plus signs Find the p-value. (Round your answer to four decimal places.) p-value = 0.6054 X What is your conclusion? O Do not reject H. There is sufficient evidence to indicate that a significant difference in preference exists. Ⓒ Do not reject Ho. There is not sufficient evidence to indicate that a significant difference in preference exists. O Reject Ho. There is sufficient evidence to indicate that a significant difference in preference exists. O Reject Ho. There is not sufficient evidence to indicate that a significant difference in preference exists. ✓
