Question 2 1 pt A researcher sets a rejection level at .05. Which of the following pvalues would he considered statistically signicant? (select all that apply). ' .04 V .01 V .03 ' .10 Question 3 1 pt Sampling error is the natural tendency of any sample, especially a small one, to be just like the population from which it was drawn. r\" True r False Question 4 1 pt A researcher sets a rejection level at .05. The p-yalue associated with the statistical test was .04. Which of the following conclusions is accurate? r The researcher should rejectthe null hypothesis r The researcher should fail to reject the null hypothesis F The researcher should reject the research hypothesis r\" The researcher should fail to reject the research hypothesis Question 5 1 pt A graduate student is interested in learning whether nurses get the recommended 78 hours of sleep a night. She mentions to her professorthat she is planning on interviewing nurses during the night shift because she has classes during the day. Her professor remarks that she might want to reconsider because night shift nurses may not be representative of all nurses. This potential issue is an example of r Measurement error Random error Sampling bias r r ' Riyal hypotheses Question 6 1 pt A researcher runs a statistical test and determines that there is no statistically significant relationship between variables and fails to reject the null hypothesis. In reality, there is a true relationship between variables. This is an example of 'H Type | Error Type II Error Random Error f. (a \"n None of the above (there was no indication of error) Question 7 1 pt We can prove if a one-tailed or two-tailed research hypothesis is absolutely true. r\" True \"n False Question 8 3 pt You are hired by a high school athletic department to examine the relationship between involvement in team sports and academic achievement among high school students. Please complete steps 1 through 3 of the hypothesis testing process. 1. State the Research Hypothesis. Be sure to indicate whether this is a onetailed or two-tailed hypothesis. 2. State the Null Hypothesis. 3. Specify the Rejection Level. Be sure to indicate why you chose this rejection level. Question 1 1 pt Previous research suggests thatthere is a relationship between happiness and stress. You want to test this relationship in a sample of social workers. You follow the required steps in the hypothesis testing process and write the following: \"It is hypothesized that as happiness increases, stress decreases among social workers.\" Which type of hypothesis is this? r\" research hypothesis rival hypothesis null hypothesis r [a r systematic hypothesis
