Answer:
On average, horses with and without enteroliths are fed the same amount of alfalfa per month
Step-by-step explanation:
Hello!
The veterinarian wants to research if eating alfalfa causes horses to have enteroliths.
The study variables are:
X₁: number of alfalfa flakes eaten over a month by a horse with enteroliths.
X₂: number of alfalfa flakes eaten over a month by a horse free of enteroliths.
She calculated a CI interval, with level 1 - α and the interval contained the cero.
With a significance level α, the hypotheses are:
H₀: μ₁ - μ₂ = 0
H₁: μ₁ - μ₂ ≠ 0
To decide whether you should reject or not the null hypothesis using a Confidence Interval is the following:
If the CI contains the number stated in the null hypothesis, the decision is to not reject the null hypothesis.
If the CI doesn't contain the number stated in the null hypothesis, then the decision is to reject the null hypothesis.
Since the interval contains the cero, if 1 - α and α are complementary, the decision is to reject the null hypothesis.
This means that at a level of significance of α, you can conclude that there is no difference between the population means of the numbers of alfalfa flakes eaten by horses with or without enteroliths.
I hope it helps!

Answer:
(x, y, z) = (2+44t, 2+14t, 7-20t)
Step-by-step explanation:
One way to write parametric equations for line L is ...
L = P + t·<em>v</em>
where P is the given point and <em>v</em> is the given direction vector. Using that form, we have ...
(x, y, z) = (2+44t, 2+14t, 7-20t)
__
If you like, you can remove a common factor of 2 from the coefficients of t.
(x, y, z) = (2+22t, 2+7t, 7-10t)
Answer:
1. Precise
2.Both
3.Precise
5.Neither
Step-by-step explanation:
Accuracy is the closeness of a measured value to a standard value.
Precision is the closeness of two or more measurements to each other.
1.The norm is 45 sit-ups in a minute.The students did, 64, 69,65 and 67. Values are not accurate compared to standard value 45.
Values are precise
Answer--Precise
2. Average score is 89.5
Scores are 89,93,91,87
Values are precise i.e a difference of 2 from each score
Values are accurate because the average score is 90 thus compared to the known average score of 89.5 they are accurate.
Answer-Both
3. Yesterday temperature=89
Tomorrow=88
Next day=90
Average =75
Values are precise i.e. difference of ± 1°
Values are not accurate compared to the average temperatures of 75 F
Answer---Precise
5. The jar contained 568 pennies
The 6 people guessed the numbers as
735,209,390,300,1005, 689
The values are not precise
The values are not accurate
Answer---Neither
