2. Compute the value of the test statistic. z=______
3. Determine the critical value(s).
4._________ the null hypothesis. At the 10% significance level, the data____________sufficient evidence to conclude that adult females are ___________ the RDA of iron, on average.
Answer:
Step-by-step explanation:
Given that the recommended dietary allowance (RDA) of iron for adult females is 18 milligrams (mg) per day. The given iron intakes (mg) were obtained for 45 random adult females.
1)
(left tailed test at 10% sigl level)
Mean difference = -3.35
2) Test statistic Z = Mean difference/std error =-5.35
3) Critical values are -1.28
Since critical value is > test statistic accept H0
4) ___Fail to reject______ the null hypothesis. At the 10% significance level, the data_____shows_______sufficient evidence to conclude that adult females are ____equal to 18 mg_______ the RDA of iron, on average.
Answer:
1,274 is correct aswer
b) How many of these delegations have all men?
c) How many of these delegations have at least one woman?
Answer:
a) 5765760
b) 60480
c) 5705280
Step-by-step explanation:
Assuming that order is not important:
Number of women = 7
Number of men = 9
Members of the delegation = 6
a) How many delegations are possible?
b) How many of these delegations have all men?
c) How many of these delegations have at least one woman?
Answer:
Step-by-step explanation:
Given
Required
The weighted average
To do this, we simply multiply each score by the corresponding worth.
i.e.
So, we have:
Using a calculator, we have:
--- approximated
Answer:
k = P - m - n
Step-by-step explanation:
The question is asking you to rearrange the equation so that k is alone on one side.
P = k + m + n
P - k = (k + m + n) - k
P - k = m + n
(P - k) - P = m + n - P
-k = m + n - P
-1(-k) = -1 (m + n - P)
k = -m - n + P
The equation is completely simplified so this is your answer.
Answer:
We have 300 edges and 200 vertices
Step-by-step explanation:
A prism is basically a 2D shape which extends into three dimensions. Thus, it has two end faces, and one face for each side on the original shape.
In addition to the two 100-sided polygons at top and bottom, the prism will also have 100 rectangular faces.
We will solve this by Euler’s formula which ks:
V - E + F = 2
where;
V is the number of vertices (corners),
E is the number of edges
F is the number of faces (of any polyhedron).
Number of vertices is 100 surrounding the top while it's 100 at the bottom. So total V = 100 + 100 = 200 .
The number of edges is 100 at the top, and 100 at the bottom. Also an additional 100 separating the hundred vertical faces.
Total number of edges is;
E = 100 + 100 + 100 = 300.
Thus, we have 300 edges and 200 vertices
