\fBefore 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. Twenty 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 (in seconds) recorded. Complete parts a through f below. Click the icon to view the data table. (a) Create a scatterplot of Transfer Time on File Size.

O A. Yes, because the scatterplot shows an approximate linear pattern. O B. Yes, because the scatterplot does not show any obvious pattern. O C. No, because the scatterplot does not show any obvious pattern. O D. No, because the scatterplot shows an obvious curved line. (b) Estimate the least squares linear equation for Transfer Time on File Size. Interpret the fitted intercept and slope.

Be sure to include their units. Note if either estimate represents a large extrapolation and is consequently not reliable. Complete the equation for the fitted line below. Estimated Transfer Time (sec) = + |File Size (MB) (Round to three decimal places as needed.) What is the correct interpretation of the intercept? Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to three decimal places as needed.) O A. The intercept of seconds is a large extrapolation and not directly interpretable. O B. The intercept is megabytes per second. For every one second increase, average file sizes increase by megabytes. O C. The intercept of seconds estimates "latency" in the network that delays the initial transfer of data. O D. The intercept is seconds per megabyte. For every one megabyte increase, average transfer times increase by seconds. What is the correct interpretation of the slope?
