calculate a confidence interval in SPSS
In your Week 2 Assignment, you displayed data based on a categorical variable and continuous variable from a specific dataset. In Week 3, you used the same variables as in Week 2 to perform a descriptive analysis of the data. For this Assignment, you will calculate a confidence interval in SPSS for one of the variables from your Week 2 and Week 3 Assignments.To prepare for this Assignment:Review the Learning Resources related to probability, sampling distributions, and confidence intervals.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you chose) from Week 2.Choose an appropriate variable from Weeks 2 and 3 and calculate a confidence interval in SPSS.Once you perform your confidence interval, review Chapter 5 and 11 of the Wagner text to understand how to copy and paste your output into your Word document.

Purdue University Unit 5 Distribution of Penny Business Statistics Discussion
Topic: Pennies for Your ThoughtsIn many of the problems from last unit, you were given information about the population. For many of the variables, you assumed the variable had a normal distribution. What if the variables you are studying are not normally distributed? Here is your challenge – if the population is not normal, can you make any inferences about that population from your random samples?As a class last unit, you have created a population of the ages of pennies. Your instructor will share this Penny Population document with you as an Excel file, that will include the histogram, mean, and standard deviation of this population of penny ages. Your instructor will also share a link to the Sampling Form to be used in step 5. See Example and DB starter video in Unit 5 LiveBinder.Main Post:1) Describe the distribution shape of the population of penny ages (i.e., left skewed, symmetric, right skewed).2) On your copy of the Penny Population document, randomly select 5 penny ages from this population. Calculate the mean of this Nickel Sample (sample size n = 5). How does this compare to the population mean?3) On your copy of the Penny Population document, randomly select 10 penny ages from this population. Calculate the mean of this Dime Sample (sample size n = 10). How does this compare to the population mean?4) On your copy of the Penny Population document, randomly select 25 penny ages from this population. Calculate the mean of this Quarter Sample (sample size n = 25). How does this compare to the population mean?5) Enter your Nickel Sample mean, Dime Sample mean, and Quarter Sample mean in the Sampling Form sent by your instructor. It will generate a histogram of the class means for each sample (Nickel Samples, Dime Samples, and Quarter Samples).6) Copy and paste the class histograms as they look so far for others to review in the discussion.Peer Reply #1: Review a classmate’s post. Respond to them as a friend. In a few sentences, explain to them what the Central Limit Theorem says referencing the mean for their Nickel Sample, Dime Sample, and Quarter Sample. See Example.Peer Reply #2: Review another classmates’ post. Respond to them as a friend. What do you notice about the shape of the histograms for the Nickel samples, Dime samples, and Quarter samples. Do any of their histograms look normal? What can you infer about a Half Dollar Sample (sample size n = 50)? See Example.Activity based on R.L. Schaeffer et al., Activity-Based Statistics

Grantham University Google stock and Standard Deviation Questions
Visit theNASDAQ historical prices weblink by typing into your browser https://finance.yahoo.com/quote/GOOG/history. We are going to be looking at a specific time period in Alphabet Inc.’s history. Set your dates by clicking on the blue dates after “Time Period”. Use a Start Date of 8/11/2018 and an End Date of 8/10/2019. Click the “Done”button.Next, click the “Apply” button. Next, click the link on the right side of the page that says “Download Data” to save the file to your computer (see graphic below).The downloaded data set will have multiple columnsand should look like the table below. Only use the column labeled “Close” and copy that data to a new spreadsheet.Make sure to copy the data to a new spreadsheet and save it either as a .xls or .xlsx file. A .csv file will not save your formulas and I need to be able to see your work. Assume that the closing prices of the stock form a normally distributed data set. This means that you need to use Excel to find the mean and standard deviation.Then, use those numbers and the z-score methods you learned in sections 6.1–6.3 of the course textbook for normal distributions to answer the questions. Do NOT count the number of data points. Complete this portion of the assignment within a single Excel file or you may use your TI calculator. Show your work or explain how you obtained each of your answers.Answers with no work and no explanation will receive no credit.If you need some assistance with the basics of using EXCEL and functions, please copy the following links into your browser and review this information:• https://support.office.com/en-us/article/excel-for...• https://support.office.com/en-gb/article/excel-fun...**For a copy of a Standard Normal Distribution Table, please see Table 5 in the Appendices of your ebook(starting on page A22).1. a) Submit a copy of your dataset along with a file that contains your answers to all of the following questions.b) What is the mean and Standard Deviation (SD) of the Closecolumn in your dataset?** USE POPULATION STANDARD DEVIATION FOR CALCULATIONS **c) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points)2. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at more than $1150 (round to two places)?(5 points)3. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $50 of the mean for that year (round to two places)? (Hint: this means the probability of being between 50 below and 50 above the mean). (5 points)4. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at lessthan $1050 per share (round to two places)?Would this be considered unusual? Use the definition that an unusual value is more than 2 standard deviations above or below the mean.(5 points)5. At what prices would Google have to close in order for it to be considered statistically unusualor statistically significant outliers? You willhave a low and high value.There are several possible definitions for unusual in statistics, but for our project let's use the definition that an unusual value is more than 2 standard deviations above or below the mean. (5 points)6. What are Quartile 1, Quartile 2, and Quartile 3 in this data set?Use Excel to find these values. This is the only question that you must answer without using anything about the normal distribution.(5 points)7. Is the normality assumption that was made at the beginning valid? Why or why not? Hint: Does this distribution have the properties of a normal distribution as described in the course textbook?Real data sets are never perfect, however, it should be close. One option would be to construct a histogram like you did in Project 1to see if it has the right shape.Something in the range of 10 to 12 classes is a good number. If you construct a histogram, please include it in your submitted response.(5points)
