UON Students Survey Probability Statistic Study Questions
In 2015 college students at a large state university completed a survey about their academic and personal life. Questions ranged from "How many credits are you registered for this semester?" to "Would you define yourself as a vegetarian?"The researcher randomly selected 325 students from the university; 312 responded to the survey.PromptThe cell-phone datafile is available in the Data section below.Once again, here is the research question for this lab.Based on a recent study, roughly 80% of college students in the U.S. own a smartphone. Is the proportion of smartphone owners lower at this university?Respond to each of the following in your initial post.State your hypotheses in symbolic form and in words. (The following should be clear in your answer: the population of interest and the meaning of the proportion p in terms of the variable Cell.)StatCrunch uses a normal model to estimate the P-value probability. Verify that normality conditions are metGive your P-value and interpret its meaning as a conditional probability.State a conclusion that answers the research question. Use a significance level of 5%. (Your answer should include the P-value and reference the population and the variable Cell.)

Liberty University Statistics K-Nearest Neighbor Classification Essay
k-Nearest Neighbor Classification
The purpose of this assignment is to perform k-Nearest Neighbor classification, interpret the results, and analyze whether or not the information generated can be used to address a specific business problem.
For this assignment, you will use the "Adult Incomes" data set from the Topic Materials.
ABC Survey Company collects data via surveys that it then sells to marketing departments. Marketing departments typically do not like missing data. Since survey takers typically do not like to answer questions regarding their salary, the one question usually missing from the survey results is, "Is your annual salary $50,000 or more?"
You are the analyst who has been tasked with finding a way to impute (i.e., fill-in) the answer to the question, "Is your annual salary $50,000 or more?" This information can best be imputed based upon how individuals answer other survey questions related to their marital status, educational level, occupation, and familial relationship status. If this important question can be accurately imputed, then the worth of the survey data provided by ABC Survey Company increases dramatically.
Question 1: Using only "Marital_Status," "Education," "Occupation," and "Relationship" variables, find the number of neighbors (k) that minimizes the error rate. Use a range of k between 3 and 10. Include the "k Selection Error Log" output when submitting the answer.
Question 2: Using the same variables and the k selected in Question 1, rerun the nearest neighbor model using the feature selection option in the IBM SPSS Modeler. What is the set of variables that minimize the error rate? Include the "Predictor Selection Error Log" output when submitting the answer.
Question 3: Using the value of k and the set of variables that minimizes the error rate, rerun the k-Nearest Neighbor model. What is the classification table? Include the pivot table output when submitting the answer.
Question 4: Consider the following individual: Marital_Status=Never-married, Education=Masters, Occupation=Sales, and Relationship=Not-in-family. Based on the k-Nearest Neighbor model from Question 3, how would this individual be classified? Provide the predicted income level (">50K" or "<=50K") and explain the process that you used to determine the income level. Include the table illustrating the data when submitting the answer.
Question 5: Describe the model building process you used to determine whether or not a particular survey taker earned an annual salary of $50,000 or more. Include discussion of the accuracy of the k-Nearest Neighbor model and how it can be used in practice to impute the answer to the question, "Is your annual salary $50,000 or more?"
