Investigation 1: Appropriateness of Inference For the following scenario, answer the questions below. Please note, do not conduct inference in this problem; just answer each question. A researcher wanted to use a random sample of 20 Spotify Songs to estimate the average Duration (in minutes) and average Tempo (in bpm) for the population of all songs on Spotify. The researcher does not have any additional information about the population of all Spotify Songs. The data set is called Song Sample1. a) Based on the above scenario, which method of statistical inference do you believe the researcher will consider to complete this estimation? Answer this question in one sentence and provide a reason for your choice. b) If we attempt to conduct statistical inference using the collected sample, what are the two parameters of interest to the researcher? Use the correct symbols and describe the parameters in context in one sentence each. c) Check the following conditions necessary to consider conducting inference using theory- based methods and the t-distribution. There are three to consider: (1) Was a random sample collected; (2) Is the population where the sample comes from normal; and (3) Is the sample size greater than or equal to 30? Check each of these conditions in one sentence. d) For the Duration variable, construct a frequency histogram in Rguroo. Remember to properly title and label the graph. Copy and paste this graph into your document. e) Describe the shape of the Duration histogram in one sentence. f) For the Duration variable, construct one horizontal boxplots in Rguroo. Remember to properly title and label the graph. Copy and paste this graph into your document. g) Does the Duration boxplot show any outliers? Answer this question in one sentence and identify any outliers if they are present. h) For the Tempo variable, construct a frequency histogram in Rguroo. Remember to properly title and label the graph. Copy and paste this graph into your document. i) Describe the shape of the Tempo histogram in one sentence. j) For the Tempo variable, construct one horizontal boxplots in Rguroo. Remember to properly title and label the graph. Copy and paste this graph into your document. k) Does the Tempo boxplot show any outliers? Answer this question in one sentence and identify any outliers if they are present. 2 1) Considering your interpretation of each variable’s graphs, is theory-based inference using the t-distribution appropriate for either variable (or both variables, or neither variable)? Answer the question and provide a reason for your response. m) If theory-based inference is not appropriate for one or both of the variables, present another possibility if the researcher still wanted to conduct statistical inference. Use one to three complete sentences in your response.
