You are tasked with enumerating the microbial load of an unknown sample. You begin your investigation by serially diluting the sample resulting in the following dilutions: 10-2, 10-3, and 10-4. You spread 95µL of each dilution onto a separate nutrient agar plate and incubate for 48 hours. Upon examining the plates for the 10-2 and 10-4 dilutions only. You observe the following results:  10-2: 240 CFU  10-4: 70 CFU  Calculate the viable titer for these two agar plates. Report your final answer in the correct notation and with appropriate units.

Problem 3: Model 2 In the second model, an interaction term between age and blood pressure level (Age*Pressure) and the Smoker dummy were related to Risk.  The following table shows the Excel output for this model (refer to this output as model 2). At the 95% confidence level, test to see whether the interaction term and the Smoker dummy variable are significant (model 2). Are they significant? Why or why not?
