Bob is curious to know which plant fertilizer, if any, will help his peppy plants to produce more peppers. He despises to test the 3 brands that the local nursery sells. He sets up four boxes and plants in each box. He gives 30g of one type of each of the three fertilizers to the first three boxes, and adds no fertilizer at all to the fourth box. What is the dependent variable in Bobs Experiment?

Four different thermometers were used to measure the temperature of a sample of pure boiling water. the measurements are recorded in the table below. thermometer temperature reading 1 temperature reading 2 temperature reading 3 w 100.1°c 99.9°c 96.9°c x 100.4°c 102.3°c 101.4°c y 90.0°c 95.2°c 98.6°c z 90.8°c 90.6°c 90.7°c the actual boiling point of pure water is 100.0°c. what can be concluded from the data about the reliability and validity of the thermometers?
