Need help making this graph with the video game data

A Similar Estimation Problem Using Data One of the learning outcomes from this course is that students will be able to SLO4: "Apply appropriate statistical models to estimate population parameters ..." In the questions below, you will be asked to estimate a population param- eter (the population mean fx) using Gossett's model for the distribution of the T statistic. A sample of 12 different video games were selected at random from a certain population of video games. The duration of game play in seconds ) for these games is listed below. Suppose we know neither the population mean nor the population standard deviation for video games of this new type, but we have good reason to believe that the duration is normally distributed (either based on past experience or based on a normality test applied to the present data) Our goal is to determine a 95 percent confidence interval estimate for the true population mean duration of game play. Let X be the duration in seconds ). Suppose we have obtained the following data relevant to our goal. video game i duration r; (in seconds 3859 3884 3 4027 4 4033 4049 4317 4318 4334 4657 4813 11 4823 12 5004 n=12 sum=52118 sum of squares 228072688 1. (1 point) Is the population standard deviation of X known to us in this problem? Answer (select one choice): 5 6 7 8 9 5 4. Either using software or working by hand, make a graph of the dis- tribution. If the sample size is bigger than 10, the graph should be a frequency histogram, otherwise just make a box plot. Hand it in along with the rest of this assignment. (See the attached instructions about submitting graphs.) The grading criteria are as follows: (1 point) Title (1 point) Axis label(s) . (1 point) Units of measurement (3 point) Numbers and shape. 5. (1 point) Looking at the graph you made, does the distribution of the data appear to be unimodal? Answer: (Select one choice.) 8
