Q III Microsoft Word - Math 1200 Project 2 Sp24.docx 2 1 / 2 - 77% + | Math 1200 - Project Exploring Data Distributions & Sampling Variability Obtain a data set with at least 100 data values and use descriptive-statistics and inferential- statistics techniques to describe characteristics of the data distribution and make statistical inferences. Prepare a report with the following information: Part 1 - Descriptive Statistics An introduction to the data set. The project involves an analysis of one quantitative variable. Source of data 45F Cloudy Search Is the data set a sample data set or a population data set? What is the level of measurement of the quantitative variable? Graphical displays of the distribution of the quantitative variable (histogram and boxplot) Use the Exploring Quantitative Data applet to construct graphical displays and find the mean and 5-number summary. https://dcmpdatatools.utdanacenter.org/eda_quantitative/ A description of the distribution (center, spread, shape, outliers). Use the 1.5-IQR Rule to explain the presence of outliers. We will consider this distribution to be a population data set, for the purpose of this study. Determine the population mean. Part 2 - Confidence Intervals Random Sample 1 Obtain a random sample of size 10 from the data distribution in Part 1. Use a random number generator to randomly obtain the data values for the sample. The website below can be used to obtain a set of random numbers. If the population data set has 1,000 values, then you should randomly find 10 numbers between 1 and 1,000. Set Minimum = 1, Maximum = 1000, generate 10 numbers, and do not sample with replacement. || = E > 9:44 PM 4/18/2024 PRE III myCT Home - PROD Experience Content Bb Microsoft Word - Math 1200 Pr G course hero - Google Search Math 1200 Project 2 Sp24.pdf + learn-us-east-1-prod-fleet01-xythos.content.blackboardcdn.com/blackboard.learn.xythos.prod/5783dfb9d7a43/39850103?X-Blackboard-S3-Bucket-blackboard.learn.xythos.prod&X-Blackboard-Expiration...

Select the data values that correspond to the random numbers to create the sample data set. List the data values in the sample. Determine the sample statistics (mean, standard deviation) of the values in the random sample. Construct a 95% confidence interval for the population mean using a T-distribution. Show your work. Does the confidence interval contain the population mean from Part 1? Random Sample 2 Obtain another random sample of size 15 from the data distribution in Part 1. Use a random number generator to randomly obtain the data values for the sample. List the data values in the sample. Determine the sample statistics (mean, standard deviation).
