An agricultural scientist decides to compare the effect three fertilizers have on the heights of a certain type of plant. For each fertilizer (A, B, and C), plants are fertilized and otherwise treated identically. After four weeks, the heights in centimeters for each plant is measured. The means are given below. Fertilizer A: 26, 28, 30 Fertilizer B: 17, 21, 16 Fertilizer C: 18, 19, 17, 18 Complete the analysis of variance table. Degrees of Freedom Sum of Squares Mean...

To study the effect of temperature on yield in a chemical
process, five batches were produced at each of three temperature
levels. The results follow.
Use a level of significance to test whether the
temperature level has an effect on the mean yield of the
process.
Calculate the value of the test statistic (to 2 decimals).

Sleep apnea is a disorder characterized by pauses in breathing during sleep. Children who suffer from untreated sleep apnea often have behavior problems, including hyperactivity, inattention, and aggression. A common treatment for pediatric sleep apnea is the surgical removal of enlarged tonsils and adenoids that are obstructing the airways Suppose researchers at a sleep clinic are interested in the effect of surgical treatment for pediatric sleep apnea on aggressive behavior. They study 11 children without sleep apnea, 11 children with...
