Answer:
We can conclude that new fertilizer appears to be more effective on apple trees.
Step-by-step explanation:
Mean and standard deviation parameters are missing in the question, I will assume amounts as below:
At Frucht Orchards, apple trees produce an average of 840 pounds of fruit per tree with a standard deviation of 120 pounds. Their mango trees produce an average of 350 pounds of fruit per tree with a standard deviation of 190 pounds. Frucht Orchards is trying two new fertilizers. An apple tree fed Amazing Apples Fertilizer yielded 940 pounds of fruit, while a mango tree fed Amazing Mangos Fertilizer yielded 400 pounds of fruit. Which new fertilizer appears to be more “amazing”?
We need to calculate standardized values (z-scores) of fertilized apple and mango trees to decide which fertilizer appears to be more "amazing".
z score for an unique value can be calculated using the equation:
z=
where
- X is the weight of the specific fruit that the fertilized trees produce.
- M is the average weight of the specific fruits that the trees produce.
- s is the standard deviation of the weights of specific fruit (583)
<u>For fertilized apple</u>
z=
≈0.83
<u>For fertilized mango</u>
z=
≈0.26
Since 0.83>0.26 we can conclude that new fertilizer appears to be more effective on apple trees.

Answer: d
Step-by-step explanation:
because in the text it states that you have to find the percentage of the budget allocated for food and round that budget to the nearest tenth and the budget is $800 so if we round 800 to the nearest tenth that would be $80.0%
