Generally, the matched sample procedure for inferences about two population means provides better precision which is independent sample approach.
Inference can be referred as steps in reasoning which involves moving to a conclusion from premises. The inference is divided into three kinds which are, abduction, deduction, and induction. The deduction is an inference which derives a logical conclusion from premises which are as assumed to be true.
The answer is, Fertilizer A = 20, Fertilizer B = 56.
<h3>What is fertilizer and example?</h3>
- Among the organic fertilizers that occur naturally are manure, slurry, worm castings, peat, seaweed, and guano. Crops made of green manure are also raised to enrich the soil with nutrients.
- Organic fertilizers also include naturally occurring minerals including mine rock phosphate, sulfate of potash, and limestone.
<h3>Set up the equations:</h3>
- Nitrogen: 8x + 5y ≥ 440.
- Phosphorous: 2x + 5y ≥ 260.
- Potassium: 4x + 5y ≥ 360.
<h3>Find the vertices:</h3>
- It is easiest to graph the equations to find the vertices. (see attachment).
- You can also solve each system of equations to find the intersected points.
<h3>The following satisfy the "greater than or equal to" requirement:</h3>
- (0, 88) = y-intercept of Nitrogen equation.
- (20, 56) = intersection of Nitrogen and Potassium equations.
- (50, 32) = intersection of Phosphorous and Potassium.
- (130, 0) = x-intercept of Potassium.
<h3>Use vertices in cost function C(x) to find the minimum:</h3>
- C(x) = $30x + $20y.
- (0, 88): $30(0) + $20(88) = $1760.
- (20, 56): $30(20) + $20(56) = $1720 = This is the minimum!
- (50, 32): $30(50) + $20(32) = $2140.
- (130, 0): $30(130) + $20(0) = $3900.
The minimum cost occurs when 20 bags of Fertilizer A and 56 bags of Fertilizer B are purchased.
