2. Dany and Jon are partners in a biology lab. They want to grow a bacterium in broth cuiture at two different pH levels [acidic or neutral] to see differences in optical density {oellsmel after 24 hours of growth. They measured 30 sampia at each pH level over several weeks and recorded the room temperature [\"C} in the lab each time. Since it was a timLLconsuming process, they took turns coilecting data and kept track of who recorded each observation in case there were any differences in how each of them measured the samples. After confirming all relevant assumptions and meancentering room temperature, they ran a ELM predicting optical density: Estimate SE I-stat pvalue 21D? 4-88 pH_acidic 5.32 1.34 p :- D.5 or p c {1135 Room Temp [centered] 0.26 0.213 p :- IDJDE or p 4: {1.05 1-15 0-9? _ p>0-050rp
