Two equal groups of seedlings, and equal in height, wereselected for an experiment. One group of seedlings was fedFertilizer A, and the other group with Fertilizer B. The meanheights of the two groups of seedlings, their standard deviations,and sample sizes are listed below. Assume simple random sampling,independence, and normally distributed data. Alpha = 0.025. SampleMean Height (inches, Std Deviation (inches), Sample Size FertilizerA 12.92, 0.25, 15 Fertilizer B 12.63, 0.20, 13 What is the nullhypothesis?
Using the data in the previous question, what is the critical tvalue using the simplified textbook method and Tables when testingthe claim that Fertilizer A is significantly greater thanFertilizer B?  Record the answer to three decimal places(x.xxx).
Using the data from the previous question, what is thet-statistic rounded off to one decimal place ? (x.x)
