11.20 Refer to Exercise 11.18. Conduct a test of the null hypothesis that b1= 0. Use a =0.05. 11.18 The extent of disease transmission can be affected greatly by the viability of infectiousorganisms suspended in the air. Because of the infectious nature of the disease under study,the viability of these organisms must be studied in an airtight chamber. One way to do this is todisperse an aerosol cloud, prepared from a solution containing the organisms, into the chamber.The biological recovery at any particular time is the percentage of the total number of organismssuspended in the aerosol that are viable. The data in the accompanying table are the biologicalrecovery percentages computed from 13 different aerosol clouds. For each of the clouds, recoverypercentages were determined at different times.a. Plot the data.b. Since there is some curvature, try to linearize the data using the log of thebiological recovery.CloudTime, r (in minutes)Biological Recovery (%)170.62552.031033.441522.052018.36.2515.173013.083510.09409.110458.311507.912557.713607.7| 11.20Refer to Exercise 11.18.
