The goal of the tests was to measure how rapidly data moved through the network given the current demand on the network. Twenty les 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 les (in seconds) recorded.

Yes, because the scatterplot does not show any obvious pattern. {:3 B. No, because the scatterplot does not show any obvious pattern. '11:} C. Yes, because the scatterplot shows an approximate linear pattern. {:2} D. No, because the scatterplot shows an obvious curved line.

Before taking the plunge into videoconferencing, a company ran tests of its current internal computer network. The goal of the tests was to measure how rapidly data moved through the network given the current demand on the network.

The slope of seconds per megabyte is a large extrapolation and not directly interpretable. O C. The slope is seconds per megabyte. For every one megabyte increase, average transfer times increase by seconds. O D. The slope of seconds is the transfer time for a file of size 0 MB. (c) Interpret the summary values r and se associated with the fitted equation. Attach units to these summary statistics as appropriate. - = with S. = with (Round to three decimal places as needed.)Before taking the plunge into videoconferencing, a company ran tests of its current internal computer network.

Select the correct choice below and ll in the answer boxes to complete your choice. (Round to one decimal place as needed.) "C- A. The value of r2 means that the equation describes about % of the variation. The value of 59 means that the standard deviation of the residuals is seconds. The value of r2 means that the equation describes about % of the variation. The value of se means that the average residual is seconds. The value of r2 means that the average residual is megabytes. The value of 59 means that the equation does not describe about % of the variation. (d) To make the system look more impressive (i.e., have smaller slope and intercept), a colleague changed the units of y to minutes and the units ofx to kilobytes (1 MB = 1,024 kilobytes). What does the new equation look like? Does it t the data any better than the equation obtained in part b? The new slope is El minutes per kilobyte. {Round to eight decimal places as needed.) lI Before taking the plunge into videoconferencing, a company ran tests of its current internal computer network.
