A researcher wishes to determine whether there is a difference in the average age of elementary school, high school, and community college teachers. Teachers are randomly selected. Their ages are recorded below. A suitable hypothesis test will be conducted to test the claim that there is no difference in the average age of each group. Find the test statistic. g
Answer:
F- test
Step-by-step explanation:
Testing the hypothesis about the equality of k (k>2) population means
Test statistic F is used to find the whether there is no difference in the average age of each group.
Test statistic to be used
F= Between Mean Square/ Within Mean Square
F= s1²/s2² where s1 and s2 are independent unbiased estimates of the variance and their values do not differ greatly.
Which have v1= k-1 and v2= n-k degrees of freedom
The analysis of variance F -t est is always a one tailed test with rejection region located in the right tail of the F- distribution.

Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.
What is circumference?A circumference gives the length around a circular object, it is the perimeter used for the circular objects.
Given that a circular tablecloth has a radius of 24 inches, we need to find the length around it,
So, the length around a circular object is its circumference,
We know that circumference of the circular object = π × diameter,
Diameter = 2 × radius = 48 inches.
So, the length around the circular cloth = π × 48
= 3.14 × 48
= 150.72
Hence Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.

3. The Manhattan Island Cruise Company sold 57
tickets for its Circle-the-Island Cruise. Each adult had
to pay $22 for the cruise and each child had to pay
$10. The company's total receipts were $774. How
many children went on the cruise?
Answer:
40 children went on the cruise.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of adults on the cruise
y is the number of children on the cruise.
57 tickets were sold:
This means that [tex]x + y = 57[/tex], and since we want the number of children y, [tex]x = 57 - y[/tex]
Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.
This means that:
[tex]22x + 10y = 774[/tex]
Since [tex]x = 57 - y[/tex]
[tex]22(57 - y) + 10y = 774[/tex]
[tex]1254 - 22y + 10y = 774[/tex]
[tex]12y = 480[/tex]
[tex]y = \frac{480}{12}[/tex]
[tex]y = 40[/tex]
40 children went on the cruise.

Solve for x. The polygons in each pair are similar.
Answer:
x = 9
Step-by-step explanation:
We need to find the value of x if the polygons in each pair are similar.
As they are similar, the ratio of their sides are equal.
The sides of first polygon are 6,12 and 4.8. On the other hand, the sides of second polygon are (2x-9) and 18.
So,
[tex]\dfrac{6}{2x-9}=\dfrac{12}{18}\\\\\dfrac{6}{2x-9}=\dfrac{2}{3}\\\\\dfrac{3}{2x-9}=\dfrac{1}{3}\\\\x=9[/tex]
So, the value of x is equal to 9.
