A 95 percent confidence interval for the proportion difference p1−p2 was calculated to be (−0. 12,0. 17). Which of the following

conclusions is supported by the interval?
SAT

The only conclusion that is supported by the interval is; C. There is evidence to conclude that p1>p2 because all values in the interval are positive.

<h3>What is the confidence Interval?</h3>

We are given a confidence interval for the difference in proportions. The null hypothesis means that there's no difference. Thus;

H0 = p1 - p2 = 0

However, If the difference is positive, it means that we have sufficient evidence as p1 > p2 but If it's negative, then we have sufficient evidence as p2 > p1.

Option A: This is incorrect because of interpretation of the interval.

Option B & D: They are not correct because they are incomplete

Option E: This is not correct because it did not properly get the definition of alpha-level and p-value with confidence interval values.

Thus, only option C is correct.

The missing options are;

A. There is evidence to conclude that p1>p2 because 0.325 is greater than 0.247.

B. There is evidence to conclude that p1

C. There is evidence to conclude that p1>p2 because all values in the interval are positive.

D. There is evidence to conclude that p1

E. There is evidence to conclude that p2>p1 because 0.247 and 0.325 are both greater than 0.05.

If there are 12 x 1023 oxygens in a sample of water, how many grams of hydrogen are in the sample?.
AveGali [126]

The amount of grams of hydrogen that are in the water sample is;

3.985 g

<h3>Avogadro's number</h3>

We are given that;

Number of moles of oxygen in a sample of water = 12 × 10²³

  • Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.

Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles

Now, molar mass of hydrogen is 1 g/mol and we know that;

Molar mass = Avogadro's number(6.023 × 10²³) moles

Thus;

6.023 × 10²³ moles = 1 g/mol

Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)

⇒ 3.985 g
