Topic 1 – Descriptive Statistics Project Directions: Use the following information to complete the questions below. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center. A researcher was interested in the anxiety present in students just prior to the midterm exam. The researcher used an anxiety self-quiz to gauge the student’s anxiety. The score for 30 students are given here. 69 99 91 66 70 98 70 53 40 58 61 66 94 77 70 56 88 85 86 40 84 86 54 48 86 43 78 53 79 89 Construct a frequency table with class, frequency, relative percent, and cumulative percent that has 6 classes to describe the distribution of the data in SPSS. Use the frequency table to construct a histogram in SPSS. Use SPSS to calculate the numerical descriptive statistics mean, median, standard deviation, and variance of the anxiety scores.

Question 1 – Descriptive Statistics Describe the distribution of credit card debt separated by gender using concepts from Unit 2 (Modules 4-7).Make an appropriate graph and provide appropriate numerical summaries. Describe the shape, center and spread using numerical measures that best describe the distribution.In your description, include an interval of typical values and a discussion of variability.Embed your StatCrunch graph in your response. Do the data suggest that males or females are more likely to have higher credit card debt?Use the data to support your answer. Question 2 – Two-Way Tables & Percentages Use StatCrunch to produce a two-way contingency table as we did in Unit 3 (Module 8).Use the row variable “gender” and column variable “class”.Analyze the data in your two-way table by finding appropriate percentages for each bullet point below. Write each conditional percentage as a ratio (e.g. 25 out of 40) and as a percentage (e.g. 25/40 = 62.5%). What percentage of students are females?What percentage of students are males and seniors?What percentage of female students are sophomores?What percentage of first-year students are male? Copy the table in your StatCrunch output window and paste it in your response. After you paste the content of your StatCrunch output window into your discussion post, keep the table titled Contingency table results and delete the Chi-Square results table. Question 3 – Confidence Intervals Of the students randomly chosen for your data set, find the percent of students that do not work any amount. Use the percentage in part a) to create a 95% confidence interval estimate for the percentage of all college students who do not work. (see concepts in Units 6 & 7 – Modules 14-19)Show your work. You can either use the math-type feature in Canvas to write out your steps or you can take a picture and upload handwritten work.Interpret your confidence interval in complete sentences. “We are 95% confident that…”What is the margin of error for the confidence interval you found?What could you do to make the confidence interval more precise/smaller?Explain using complete sentences. Question 4 – Hypothesis Tests Based on a recent study of college students, the average student loan debt amount is $4000. Is the mean student loan debt higher at StatCrunchU? Include each of the following in your response. (see concepts in Units 7 & 8 – Modules 17-23)State your hypotheses in symbolic form and in words.Verify that normality conditions are met. Which test are you using? Why?Use StatCrunch to conduct the hypothesis test. Copy and paste the results (the StatCrunch output window) into your response.Give your P-value and interpret its meaning.State a conclusion that answers the research question. Use a significance level of 5%. this is the Data sethttps://www.statcrunch.com/app/index.php?launch=st...
