- You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly larger than 53% at a level of significance of a = 0.10. According to your sample, 42 out of 69 potential voters prefer the Democratic candidate. a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? ✓ Select an answer H₁: ? Select an answer (please enter a decimal) (Please enter a decimal) c. The test statistic ? d. The p-value = e. The p-value is ? ✓ a f. Based on this, we should Select an answer the null hypothesis. (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.)It is recommended that adults get 8 hours of sleep each night. A researcher hypothesized college students got less than the recommended number of hours of sleep each night, on average. The researcher randomly sampled 50 college students and calculated a sample mean of 7.9 hours per night. The researcher performed a hypothesis test. What is the null hypothesis? ..... Choose the correct answer below. O A. Ho: Hx <7.9 hours per night В. Но: Их = 7.9 hours per night O C. Ho: Hx < 8 hours per night O D. Ho: Hx = 8 hours per nightA 2011 survey, by the Bureau of Labor Statistics, reported that 91% of Americans have paid leave. In January 2012, a random survey of 880 workers showed that 89% had paid leave. The resulting p-value is 0.0072; thus, the null hypothesis is rejected. It is concluded that there has been a decrease in the proportion of people, who have paid leave from 2011 to January 2012. What type of error is possible in this situation? type I type II neither O both
- You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly different from 69% at a level of significance of a = 0.05. According to your sample, 59 out of 75 potential voters prefer the Democratic candidate. a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho:? v|| Select an answer v (please enter a decimal) H1: ? v Select an answer v (Please enter a decimal) c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that...A statistical test of hypothesis produces the P-value P = 0.0467. Will the null hypothesis be rejected at the 0.05 level of significance? Explain in 1-2 complete sentences.Last year's mean hourly wage (in dollars) for all hospital clerical workers in a large state was 8. An administrator for the state believes that this year's mean hourly wage for hospital clerical workers is greater than last year's mean. She hires statisticians to sample a number of hospital clerical workers and to carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that would be used for this test. H. 文 H. OO ロ=ロ ローロ
- You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.69.

The data suggest the populaton proportion is significantly larger than 53% at a = 0.05, so there is sufficient evidence to conclude that the population proportion of students who played intramural sports who received a…
- Suppose that we reject a null hypothesis at the 0.001 level of significance. The null hypothesis will definitely also be rejected for all the following a- values except for: A. 0.01 B. 0.0005 C. 0.005 D. 0.05 E. 0.002Suppose the null hypothesis, Ho, is: the mean age of the horses on a ranch is 6 years. What is the Type lI error in this scenario? Select the correct answer below: O O O O You think the mean age of the horses on a ranch is 6 years when, in fact, it is. You think the mean age of the horses on a ranch is 6 years when, in fact, it is not. You think the mean age of the horses is not 6 years when, in fact, it is. You think the mean age of the horses is not 6 years when, in fact, it is not.suppose a hypothesis test is conducted where the level of significance a= 0.05 and the test results in p- value = 0.04 should the researcher reject the null hypothesis? A. yes because the p-value is less than a b. no should not reject because the p-value is greater than a c. no should not reject because is less than a d. yes should reject because the p-value is greater than a
