1 In-Service Program for Nurses Using the paper linked on D2L under the heading \"Inservice Program for Nurses\" answer the following questions: a) b) C) d) E) f) g) 1What is the total number of the research participants in the study? In Table 3, which p-values are significant and which are not? Why was the Mann-'Whitnenyilcoxon Rank Sum Test and not the standard t-test used to examine the difference in research participation between the two groups? In Table 3, what comparison demonstrated the greatest significant difference between the groups? Provide a rational for your answer. Does the p-value of the pretest enhance or diminish the validity of the findings? Provide a rationale for your answer. 1What might have been the reason why the researchers did not treat the participation questionnaire data as continuous data (by using the subjects' total scores on the questionnaire) and conducted t-tests instead of the Mann- WHIEYMHCOXOD Rank Sum Test as they did when nurses' attitudes towards research were examined? (Hint: Look at the median scores and compare them to the range.) If the researcher ran a skewness analysis on the distribution of scores presented in Table 3 and found that the distribution was skewed, would the data be positively (right) skewed or negatively (left) skewed
