Question 13 Test the claim that a population proportion is more than 0.9. A random sample of 70 trials yields 69 successes. Use a = 0.05. 1. To confirm that the sample is large enough, there must be at least 5 successes and 5 failures. We are okay here, since there are 69 successes and failures. The hypotheses are: O Ho: / 2 0.9; Ha: p 0.9 O Ho:u = 0.9; Ha:u # 0.9 O Ho:p 0.9 2. This is a O right left two tailed test and the distribution used is O T since o not known O Z since o known O Z since testing a proportion The Degrees of Freedom are O 70 O 69 O N/A since this is a Z-test3. The STS {round to 3 decimals} is: The P-value {round to 4 decimals} is: 4. The decision at or = 0.05 is: '33:? Reject Ho since P :5. a '3' Do not reject Ho since P > o: '3' Reject Ho since P :3 a '3' Do not reject Ho since P 31 o: The conclusion is: '5'} There is insufficient evidence to conclude that the proportion is not more than 0.9 ""333 There is sufficient evidence to conclude that the proportion is not more than 0.9 '37:? There is sufficient evidence to conclude that the proportion is more than 0.9 3":3' There is insufficient evidence to conclude that the proportion is more than 0.9
