The manager of a URL commercial address is interested in predicting the number of megabytes downloaded, megasd
, by clients according to the number minutes they are connected, mconnected
. The manager randomly selects (megabyte, minute) pairs, and records the data. The pairs (megasd
, mconnected
) are stored in the data frame URLADDRESS
.
URLADDRESS
A data frame with 30 observations on the following 2 variables:
megasd
(megabytes downloaded)
mconnected
(number of minutes connected)
