The appropriate hypotheses for this test are :
- Erica filled 70
- Jen filled 10
- Heather filled 10
- Tonya filled 10
<h3>Meaning of hypothesis</h3>
A hypothesis is a statement that proposes a result that will be tested to get a verified result.A hypothesis is not hundred percent true, that is why it is always put to test. Hypothesis is singular while hypotheses is plural
Making a hypothesis in this case is an attempt to predict an answer or result that will be verified by doing the experiment.
We can conclude by saying that a hypothesis is not hundred percent true.

exhibit population for ten integers is 15,19,19,20,20,20,21,22,22,22 mean is 20 variance is 4
Step-by-step explanation:
- Mean is helps in finding the mid point of the data.
- Variance is the variability of data it was here.
- In order to get the data straight the combination of 4 was required.
- 4 is variance one data set was 19 other had to be 22.
- As mean is 20 three means had to be 20.
- from mean 20 4 is greater then 20 and 3 is less then 20.
- 15 being the lowest it compensated the variance to 4.
- Mathematically there are many ways to do this using function.
- This is to be found out at a traditional method.
- Reducing or increase the number as it was integers.
Answer:
Step-by-step explanation:
(x + 4)/(x+4)(x-3)
= 1/(x-3)
solution is option 4
Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
