A data engineer working for The Gabba Stadium has recorded the number of people attending AFL events in 2018. This data has been provided on Blackboard in a.csv file (GabbaAttendance.csv). The data engineer claims that the average attendance at an event is 15,000 people and your task is to determine whether this is valid or not, by following the steps below 1. Using MATLAB, import the data using csvread and determine the number of...

Please use MATLAB.
Part B (Based off week 11 workshop content) An engineering company has ordered steel to be used for a rail construction project. Before using the steel, they want to test it to ensure the material properties from the supplier are correct A random sample of the ordered steel is tested for its Yield Strength. The results are shown below. Yield Strength (MPa) 197203194196196197198205 1. Calculate the sample mean and sample variance by hand, then verify your answers...

Suppose a teacher recorded the attendance of her students in a recent statistics class because she wanted to investigate the linear relationship between the number of classes they missed and their final grades. The accompanying table shows these data for a random sample of nine students. Complete parts a through c. Click the icon to view the table showing missed classes and final grade. a. Using a =0.02, test the significance of the regression slope. The hypotheses for this test...
