The performances of a group of interns are evaluated by T The performances of a group of interns are evaluated by their supervisors at the end of their internships. Their scores are: 55, 47, 62, 27, 50, 49, 66, 53, 50, 44, 63, 59. Complete the calculations below using this data. Show all of your work and clearly label each of your calculations. the mean the median the range the standard deviation the variance The Anxiety General Stress Test (ANGST) has been designed to gauge the level of psychological stress management trainees experience when they are under pressure. For a random sample of trainees, the scores are as follows: 47, 49, 53, 53, 54, 58, 61, 64, 75, 81. Complete the calculations below using this data. Show all of your work and clearly label each of your calculations. What is the z score equivalent of ANGST = 81? What is the probability that someone selected at random will score 81 or lower? What percentage of all trainees will score between 60 and 75? Copy and paste your calculations for the three problems from Excel to Word and submit one Word document with your clearly labeled calculations and interpretations.
Paper For Above instruction ### Introduction Statistical analysis plays a crucial role in evaluating performance metrics in research and practical applications. This paper details the computation of key descriptive statistics—mean, median, range, variance, and standard deviation—for two data sets. The first data set encompasses scores of interns evaluated at their internship completion, while the second set pertains to scores from the Anxiety General Stress Test (ANGST). Moreover, the paper applies inferential statistics to determine Z-scores, probabilities, and percentages related to the ANGST scores, offering insights into stress levels among trainees. Accurate calculation and interpretation of these statistics provide valuable tools for assessing performance and psychological states in educational and clinical settings. ### Analysis of Intern Performance Scores The first data set includes intern evaluation scores: 55, 47, 62, 27, 50, 49, 66, 53, 50, 44, 63, 59. To analyze these, the calculations for central tendency and variability are performed step by step. **Mean Calculation:** The mean score, a measure of central tendency, is computed by summing all scores and dividing by the
