In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. The calculated value for the test statistic equals
Answers
Answer:
The test statistic for Business College is -0.9944
The test statistic for Liberal Arts College is 1.1483
The test statistic for Education College is 0
Step-by-step explanation:
The percentage of ABC University college students in
Business College = 35%
Liberal Arts College = 35%
Education College = 30%
The number of students in the sample = 300 students
In the sample, the number of students in;
Business College = 90
Liberal Arts College = 120
Education College = 90
Therefore;
The percentage of Business College students = 90/300 × 100 = 30%
The percentage of Liberal Arts College, = 120/300 × 100 = 40%
The percentage of Education College, [tex]\hat p[/tex] = 90/300 × 100 = 30%
The test statistic for the difference in two proportions is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]
Where;
[tex]\hat p[/tex] = The sample proportion
p = The population proportion
q = 1 - p
n = The sample size
The test statistic for Business College is;
[tex]z=\dfrac{0.3-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{90}}} \approx -0.9944[/tex]
The test statistic for Liberal Arts College is;
[tex]z=\dfrac{0.4-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{120}}} \approx 1.1483[/tex]
The test statistic for Education College is;
[tex]z=\dfrac{0.3-0.3}{\sqrt{\dfrac{0.3 \times 0.70}{120}}} \approx 0[/tex]
Answer:
Using the Chi-Square test we find test statistic equals 4.29
Step-by-step explanation:
Start by calculating the expected value:
35% Business College = 0.35 x 300 = 105
35% Liberal Arts College = 0.35 x 300 = 105
30% Education College = 0.3 x 300 = 90

Answer: Option 'D' is correct.
Explanation:
We are required to find that length of sides which cannot be sides of triangle,
As we know that " Sum of two sides is always greater than the third side "
If any option does not follow the above postulate that will be our required answer :
D) 21 m, 6 m, 10 m
So, 21 m, 6 m, 10 m cannot be the length of any triangle as it does not satisfy the above mentioned postulate .

It is C because if you multiply each number on the left by 250 and then add 500, you will get the number on the right.
4 x 250 = 1000 + 500 = 1500
8 x 250 = 2000 + 500 = 2500
10 x 250 = 2500 + 500 = 3000

For which value of x is the row in the table of values the incorrect? The function is quadric function y=5x^2
A. x=5
B. x=0
C. x=3
D. x=2
Answers
Answer:
x = 2
Step-by-step explanation:
Substitute x = 2 into y = 5x² , that is
y = 5(2)² = 5(4) = 20 ≠ 10
Thus (x, y ) = (2, 20 ) and not (2, 10 )

A) X = 5, y = 15
B) x = 15, y = 5
C) x = 30, y = 60
D) x = 60, y = 30
Answers
Answer:
A) X = 5, y = 15
Step-by-step explanation:
De la figura:
∠EHD = ∠EGB (los ángulos correspondientes son iguales). Por lo tanto;
18x-2y = 60 (1)
Además, ∠CHF = ∠EHD (los ángulos opuestos serticales son iguales). Por eso;
18x-2y = 9x + y
18x-9x-2y-y = 0
9x-3y = 0 (2)
Para resolver x e y, resolvemos la ecuación (1) y (2) simultáneamente.
Multiplique la ecuación (2) por 2 y reste de la ecuación (1):
4 años = 60
y = 15
Pon y = 15 en la ecuación (2):
9x-3 (15) = 0
9x-45 = 0
9x = 45
x = 5
