Read the following hypotheses:• Confidence in recall differs depending on the level of stress.●Recall for participants in high-stress conditions will deteriorate over time.• Boys will have higher levels of confidence than girls.for each hypothesis listed above, indicate:Describe how a Type I error might occur, given the context of the assignment.Describe how a Type Il error might occur, given the context of the assignment(i.e., if my hypothesis was that women had higher levels of empathy than men, aType I error might occur if I found significant results with women scoring higheron empathy than men, when, in the general population that is not the case, aType II error might occur if I found no differences in empathy between men andwomen when, in the general population women score higher on empathy thanmen).Whether the appropriate analysis would be a one-tailed test or a two-tailed test●

Data were collected from 400 patients in the US about their estrogen level. Out of the 400, 35 patient have abnormal estrogen levels. On a national level, 8 % of patients have abnormal estrogen level. Researchers want to know the sample proportion differs from the national level. 5% is used for significance. Give the Ho and Ha. The appropriate test. Decision rule. Test calculations. Conclusion with comparison to alpha or critical value. I think this is a two tailed test. Use a one sample t- test. I think the null is rejected. t (40-1) = (400-35) / (.05 divided by sqrt 31) This is where I get stuck.

A common idea is that people can temporarily postponed death to survive a major holiday or important event. A study found that there were 6907 deaths before Thanksgiving and 5739 deaths after Thanksgiving.

You suspect that drivers for Uber/Lyft have newer cars than a driver who doesn’t drive for Uber/Lyft. Listed below are the ages of cars that you randomly sampled from the streets of Portland. If one were to conduct a hypothesis test for the difference in mean car age and mean Uber/Lyft car age, the conditions for the test would need to be checked. What conditions should you check? Check the conditions and explain how the conditions are met or not. What is the appropriate test to conduct, an independent samples t test or paired t test? Explain.
