Answer:
Step-by-step explanation:
Information provided
n=100 represent the random sample taken
X=21 represent the number of bags overfilled
estimated proportion of overfilled bags
is the value that we want to test
z would represent the statistic
Hypothesis
We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
And replacing the info given we got:
Coordinates of the center you can find from
x-3=0 and y+5=0
x=3 and y=-5
(3,-5) is the center of the circle.
25 is a square of the radius.
r²=25, so
r=5
Center (3,-5), r=5
So, the answer is D.
Answer:
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Alternative hpothesis Hₐ: ∪ > 393 pounds
Step-by-step explanation:
The null hypothesis in this case is
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Agriculture Scientists wish to test against this claim believing that the new fertilizer may increase the yield, thus the alternative hypothesis will be
Alternative hpothesis Hₐ: ∪ > 393 pounds.
