Consider a modern packet-switched network of three hops between a source host and a destination host, as shown in the figure below. source host —- packet switch —- packet switch —- destination host   The source host needs to send a message of 1,000,000 bits long to the destination host. The source host segments the message into smaller packets of 1000 bits each and sends the packets through the network. The destination then reassembles the packets back into the original message. Suppose the bandwidth of each link in the above figure is 1 Mbps. Suppose the propagation delay of each link is 1ms. Ignore queuing and processing delays. How long does it take to transfer the entire message from the source host through the network to the destination host when message segmentation is used?

Describe any asymptotes and/or holes for the function.

You want to design a Randomized Control Trial to evaluate the treatment effectiveness of VMO training during closed kinetic chain exercises for patients with patella-femoral pain. Three groups will be compared: a control group (no treatment), a group with general exercise programs and a group with a specific program designed based on closed kinetic chain exercises for VMO.  Although as part of the sampling process a computer randomization has been planned, you are afraid that the variables of gender and previous physical activity might alter your results. What statistical analysis will help to control for the presence of this confounding variable?  

The average cost (COST) of heating a home is a function of outside Temperature (TEMP), thickness of Insulation (INSUL) and Age of furnace (AGE). Data is collected on these variables and a regression analysis is done on the data. An incomplete MS Excel output is shown below.   Regression Statistics         Multiple R           R Square           Adjusted R Square           Standard Error           Observations                        ANOVA             df SS MS F Signifcance F Regression   171220       Residual           Total 19 212916                     Coefficients Standard Error t Stat P-Value Lower 95% Intercept 427 59.6 7.17     TEMPT (X1)   0.7723 -5.93     INSUL (X2) -14.8 4.754       AGE (X3) 12.1 4.012         The hypothesis to be tested is:
