Answer:
1 cup of milk = 3cups of brown sugar
Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575

Answer:
quadratic equation by graphic method
Step-by-step explanation:
I think the average would increase by $1,650. 5% of 33000 is 1,650. So the the total amount would increase by that.
The conclusion for p, from the confidence interval, using an absolute value inequality is:
<h3>What is a confidence interval?</h3>
A confidence interval is given by the <u>estimate plus minus the margin of error</u>. As an inequality, we have that the absolute value of the difference between the proportion and the estimate is of at most the margin of error, that is:
For this problem, the estimate and the margin of error are:
E = 0.27, M = 0.019.
Hence the inequality is:
