A company ran tests of its current internal computer network. Thirty files ranging in size from 20 to 100 megabytes (MB) were transmitted over the network at various times of day, and the time to send the files recorded, as shown in the accompanying data table. Formulate the regression model with Y given by Transfer Time and X given by File Size. Time Flei size (sec) (MB) 28 12.2 71 25.4 88 29.9 73 27.8 471 18.2. 44 21.30 83 31.1. 49 22.9 70 26.7 74 24.4 25 13.8. 94 33.1 62 23.7 48 19.4 87 29.9 30 17.3 83 30.1 40 17.3 22 14.6 20 12.1 66 25.7 80 31.1 Copy-and-paste the above data into software of your choice. Run a regression analysis using y = time and x = file size. What is the regression equation? Round to the nearest hundredth (2 decimal places). time = A A x file size. Find the value of the t-statistic for the hypothesis test of zero slope. What is the value of this t-statistic, rounded to the nearest whole number? t = A What is the appropriate conclusior to the hypothesis test of zero slope? At the 5% significance level, A the null hypothesis of zero slope. (Type the word reject or phrase fail to reject.) Using the regression equation, what is the predicted transfer time for a 73 MB file? Round to the nearest whole number. A 73 MB file is predicted to have a transfer time of A seconds
