Answer:
Yes. Fertilization increases grape yields by more than 5 pounds.
Step-by-step explanation:
Let f-fertilized and o-old(unfertilized)
#First, we use our data to calculate the standard error:
#State both null and alternative hypothesis:
#We determine our degrees of freedom as 87.02(using R), we now compute the t-value as:
Since, the p-value is low, we Reject the null hypothesis. The is enough evidence suggesting that grape yields increase by more than 5 pounds than mean yields of unfertilized grapes.
Hello from MrBillDoesMath!
Answer:
y = 2x + 2.5
Discussion:
2y -4x = 5 => add 4x to both sides
2y - 4x + 4x = 4x + 5 => -4x + 4x = 0
2y = 4x + 5 => divide both sides by 2
y = 2x + (5/2) => as 5/2 = 2.5
y = 2x + 2/5
Thank you,
