[SOLUTION] Standard Error of the Mean

Standard Error of the Mean. What is the standard error of the mean for the following values sampled from the population of Seattle robberies: 426, 445, 603, 579, 543. (Also treat these five numbers as a population when calculating their standard deviation)?9. (5 points). Standard Error Z-scores & Area under the curve.a. What is the Z-score associated with the standard error of the mean you calculated in question 8?b. What percentage of a normal distribution would we expect to fall between the Z-score for the standard error of the mean and a Z-score of 0?Dataset: The dataset for this portion of the assignment is data from the Seattle Public Safety Survey and is labeled Safety_Survey_Midterm.sav. IMPORTANT: Use only the dataset linked from the Assignments page where the Midterm information is located and where you downloaded this document.There are multiple variables that capture information about the respondents and their views on public safety related issues in the Seattle area. To be eligible to complete the survey, respondents need to live and/or work in Seattle. Please type your answers directly into this document and insert all graphs and tables requested into this document. In addition, save your output and submit it with this file.10. (5 points). Create two pie charts that compare the distribution of individuals who did not report their victimization (NO_REPORT) between whether the respondent identified as female or not (FEMALE). Edit the graph so that it is presentable and copy and paste it into this document. Explain what differences, if any, do you see between the two pie charts.11. (5 points). Create a scatterplot that explores the relationship between a respondent’s perception of social disorganization in their neighborhood (SOCIAL_DISORGANIZATION_SCALE) and their fear of crime (FEAR_CRIME_SCALE). Social disorganization measures a respondent’s perception of visible problems in their neighborhood, such as broken windows, graffiti, etc… Fear of crime measures how often they think about, or are fearful of, criminal victimization. Edit the graph so that it is presentable and copy and paste it into this document. What trends do you see in the data? Offer an explanation for why you think that might be.12. (5 points). Using the year the respondent completed the survey (SURVEY_YEAR) and whether the respondent was victimized or not (VCTM_YES), create a multiple line graph. Edit the graph so that it is presentable and copy and paste it into this document. Interpret your graph for me (i.e. explain the patterns you see in the data).13. (5 points). Using the variable for social cohesion (SOCIAL_COHESION_SCALE) request and report on the three main measures of central tendency we discussed in class as well as the three measures of variability/dispersion.14. (5 points). Request frequency tables for marital status (MARITAL_STATUS) and the age of the respondent (AGE). Answer the below questions.a. What is the mode for marital status?b. What % of respondents were single?c. For respondents who provided information about their age, what percent were younger than 60?d. What is the scale of measurement for age?
