A farmer wants to test if a new fertilizer increases the yield of his tomato plants. He applies the new fertilizer to a group of 10 plants (Group A) and uses the standard fertilizer on another group of 10 plants (Group B).
Group A (New): 5.2, 5.5, 5.8, 6.1, 5.9, 6.3, 5.7, 6.0, 5.4, 5.6 kg
Group B (Standard): 4.8, 5.0, 4.9, 5.2, 5.1, 5.3, 4.7, 5.0, 4.9, 5.1 kg
Test at the \(1\pourcent\) significance level whether the new fertilizer produces a
higher
mean yield.
