Data from drug stability study shows non-linear relationship between storage time and the concentration of degradation product in tablets. That relationship is best described by an exponential equation C=C0*exp(k*t) , where t – storage time (in months), C and C0 are current (at time t) and initial concentrations of the degradant, respectively; and k – reaction constant. We have the data for C, C0 and t for multiple tablet samples measured every 6 months over 36-months period. Can we use the linear regression method to estimate the reaction constant k from that data? Please explain.

Table 1 shows the temperature-time data were recorded for the reaction between 50.0 mL of 1.18 M HA (a weak acid) and 50.0 mL of 0.98 M NH4OH, ammonium hydroxide (a weak base, also known as aqueous ammonia). The solutions were mixed after 60 s of approximately constant temperature readings of 24.20 oC. This is the initial temperature.

We assume that our wages will increase as we gain experience and become more valuable to our employers. Wages also increase because of inflation. By examining a sample of employees at a given point in time, we can look at part of the picture. How does length of service (LOS) relate to wages? The data here (data238.dat) is the LOS in months and wages for 60 women who work in Indiana banks. Wages are yearly total income divided by the...
