You are a research assistant at a zoo.  The question of your study is "Has the proportion of baby zebras born in zoos increased from 10%?".  Your supervisor asks that you run a hypothesis test using an significance level of 0.05.  Form the study you obtain a z-score of 0.788.  Do you reject the null hypothesis and why?  A) Yes, you reject the null hypothesis.  The obtained z-score is in the area of rejection.   B) No, you retain the null hypothesis.  The obtained z-score is not in the area of rejection.  C)  Yes, you reject the null hypothesis.  The obtained z-score is not in the area of rejection.   D) No, you retain the null hypothesis.  The obtained z-score is in the area of

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 0.29. You use a significance level of a = 0.02. Но: р Нi:р> 0.29 0.29 You obtain a sample of size n 555 in which there are 195 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = || The p-value is... less than (or equal to) a greater than a This test statistic leads to a decision to... O reject the null O accept the null

You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.23. You use a significance level of a = 0.001. Ho:p > 0.23 HA:P < 0.23 You obtain a sample of sizen = 130 in which there are 18 successes. What is the test statistic for this sample? (Round the answer to two decimal places.) test statistic = What is the p-value for this sample? (Give the answer to four decimal places.) p-value = The p-value is... less than (or equal to) a greater than a This test statistic leads to a decision to... reject the null hypothesis, Ho accept the null hypothesis, Họ | fail to reject the null hypothesis, Ho As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the accuracy rate for fingerprint identification is less than 0.23. | There is not sufficient evidence to warrant rejection of the claim that the accuracy rate for fingerprint identification is less than 0.23.
