A local arts council has 200 members. The council president wanted to estimate the percent of its members who have had experience in writing grants. The president randomly selected 30 members and surveyed the selected members on their grant-writing experience. Of the 30 selected members, 12 indicated that they did have the experience. Have the conditions for inference with a one-sample z -interval been met
Answers
Answer:
Yes the sample can be use to make inference
Step-by-step explanation:
The inference is possible if the conditions:
p*n > 10 and q*n > 10
where p and q are the proportion probability of success and q = 1 - p
n is sample size
Then p = 12 / 30 = 0,4 q = 1 - 0,4 q = 0,6
And p*n = 0,4 * 30 = 12 12 > 10
And q*n = 0,6 * 30 = 18 18 > 10
Therefore with that sample the conditions to approximate the binomial distribution to a Normal distribution are met
To check the condition for inference with a one sample z-interval, we have to divide randomly selected member by total number of arts council.
No, the sample size is not less than 10% of the population size,
Given:
The total number of council member are 200.
The randomly selected members are 30 .
Calculate the ratio of randomly selected members and total number of council member.
[tex]\dfrac{n}{N}=\dfrac{30}{200}\\\dfrac{n}{N}=0.15\\\dfrac{n}{N}=0.15>0.10[/tex]
Thus, No, the sample size is not less than 10% of the population size.

Three co-workers recorded the amount of water in a fish tank being replaced at regular intervals.
maggie measured 1/2 gallon of water in 2/3 of an hour.
christine measured 3/4 gallon of water in 6/5 of an hour.
gianna measured 2/3 gallons of water in 4/5 of an hour.
What two statements are true?
A. Giannas fish tank replaced the most water per hour.
B. Christies fish tank replaced the most water per hour.
C. Christies fish tank replaced the least water per hour.
D. All three fish tank replaced more than one gallon of water per hour.
E. Two of the fish tanks almost replaced the same amount of water per hour.
Answers
Answer:
A. Giannas fish tank replaced the most water per hour.
C. Christies fish tank replaced the least water per hour.
Step-by-step explanation:
Let define the replacement rate ([tex]r[/tex]), measured in gallons per hour, by the ratio of capacity ([tex]c[/tex]), measured in gallons, to replacing time ([tex]t[/tex]), measured in hours. That is:
[tex]r = \frac{c}{t}[/tex] (1)
The co-worker with the highest rate replaces the most water in a hour. Let see the rate of each co-worker:
Maggie ([tex]c = \frac{1}{2}\,gal[/tex], [tex]t = \frac{2}{3}\,h[/tex])
[tex]r = \frac{\frac{1}{2}\,gal }{\frac{2}{3}\,h }[/tex]
[tex]r = \frac{3}{4}\,\frac{gal}{h}[/tex]
[tex]r = 0.75\,\frac{gal}{h}[/tex]
Christine ([tex]c = \frac{3}{4}\,gal[/tex], [tex]t = \frac{6}{5}\,h[/tex])
[tex]r = \frac{\frac{3}{4}\,gal }{\frac{6}{5}\,h }[/tex]
[tex]r = \frac{15}{24}\,\frac{gal}{h}[/tex]
[tex]r = \frac{5}{8}\,\frac{gal}{h}[/tex]
[tex]r = 0.625\,\frac{gal}{h}[/tex]
Gianna ([tex]c = \frac{2}{3}\,gal[/tex], [tex]t = \frac{4}{5}\,h[/tex])
[tex]r = \frac{\frac{2}{3}\,gal }{\frac{4}{5}\,h }[/tex]
[tex]r = \frac{10}{12}\,\frac{gal}{h}[/tex]
[tex]r = \frac{5}{6}\,\frac{gal}{h}[/tex]
[tex]r = 0.833\,\frac{gal}{h}[/tex]
From these informations, we conclude that Gianna's fish tank replaced the most water per hour and Christine replaced the least water per hour. All three fish tanks replace less than one gallon of water per hour. Therefore, correct answers are A and C.

Length per strip = 1/6
Fraction of paper left = 2/3
Number of strips that can be cut from the Fraction left ;
Fraction left ÷ length per strip
2/3 ÷ 1/6
2/3 * 6/ 1

Which gives 28 + 24 as a product of the GCF and a sum?
a. 2 (14 + 12)
b. 4 (7 + 6)
c. 2 (26 + 22)
d. 40 + 12
Answers
Answer:
b. 4 (7 + 6)
Step-by-step explanation:
Finding the GCF between 28 and 24:
We keep dividing while both numbers can be divided by the same factor. So
28 - 24|2
14 - 12|2
7 - 6
There is no number for which 7 and 6 are both divisible by, so the GCF between 28 and 24 is 4.
Simplifying in function of the GCF:
Now, we put 4 in evidence, and divide the rest of the expression by 4. So
[tex]28 + 24 = 4(\frac{28}{4} + \frac{24}{4}) = 4(7 + 6)[/tex]
The answer is given by option b.

Answer:
Step-by-step explanation:
It is a vertical parabola. The equation of a vertical parabola can be written in the form y = a(x-h)² + k, where a>0 and (h,k) is the vertex.
You can eliminate G and I because the leading coefficient is negative.
The graph isn't marked with units, but both F and H say that the vertex is at (0,-2), so you know that each square on the graph is one unit.
Now look for another clue.
The x-intercepts are at (-1,0) and (1,0). Plug one of the points into F and H.
F: 0 = 2·1² - 2
H: 0 ≠ 1² - 2
So, F represents the graph.

If p varies inversely as Q2 and p = 4 when Q =0.5, find p when Q = 1.5
Answers
Answer:
a) k = 8
b) p = 12
Step-by-step explanation:
Step(i):-
Given that p varies inversely as Q
p∝ Q
p = k Q
Given that p = 4 and Q = 0.5
4 = k (0.5)
k = [tex]\frac{4}{0.5} = 8[/tex]
Step(ii):-
Given that Q = 1.5
p = k Q
p = 8 (1.5)
p = 12
