Concept explainers
Bioreactor production of antibodies. Benchtop bioreactors are used to produce antibodies for anti-cancer drugs. Engineers calibrate bioreactors in order to maximize production. The African Journal of Biotechnology (December 2011) published a study designed to achieve a high percentage of antibody production from a bioreactor. The variable of interest was the natural logarithm of the number of viable cells produced in a bioreactor run. Data were collected for a sample of four bioreactor runs every 6 hours for 20 consecutive time periods. These data (simulated from information provided in the article) are listed in the accompanying table. Engineers have specified the following for the bioreactor runs: target mean = 6.3, LSL = 5.9, and USL = 6.5. Run a complete capability analysis on the data. How would you categorize the performance of the process?

- What might a scatterplot of data points look like if it were best described by a logarithmic model?arrow_forwardWhat does the y -intercept on the graph of a logistic equation correspond to for a population modeled by that equation?arrow_forwardSales of a video game released in the year 2000 took off at first, but then steadily slowed as time moved on. Table 4 shows the number of games sold, in thousands, from the years 20002010. a. Let x represent time in years starting with x=1 for the year 2000. Let y represent the number of games sold in thousands. Use logarithmic regression to fit a model to these data. b. If games continue to sell at this rate, how many games will sell in 2015? Round to the nearest thousand.arrow_forward
