Answer:
statistical hypothesis.
Step-by-step explanation:
A statistical hypothesis has the central objective of assisting in a decision-making process about one or more populations in relation to the sample data, allowing the observance of whether the information found in the samples will support the statistical hypothesis.
It is necessary to know concepts of mathematical probability to perform the tests, the most used models for this purpose are the fisher method, by Neyman-Pearson and Bayes.
The variables used in a statistical hypothesis are: the Null Hypothesis, the one that is assumed to be the true one, the Alternative Hypothesis, the one that is used when there is no statistic to analyze the hypothesis given as true, the Type I Error, related to the probability of rejection of the null hypothesis, and the Type II Error, which is the probability of rejection of the alternative hypothesis if it is true.
Answer:
0.0000015
Step-by-step explanation:
He answer is subjective probability. Subjective probability is when it has no prior calculations and the person is just guessing. Theoretical probability is when it’s based on prior calculations. Experimental probability is when you experiment and calculate.
Answer: x= 0.18779342
Step-by-step explanation:
Vertex: (-5,-2); parabola opens up;
General form of the equation for a vertical parabola opening up is:
y-k = a(x-h)^2; knowing that the vertex is at (-5,-2), we can write:
y+2 = a(x+5)^2. We need to find the value of the coefficient a.
From the graph we see that y is 10 when x is approx. -1 3/4 (or -7/4).
subst. these values into y+2 = a(x+5)^2, we get:
10 + 2 = a(-7/4 + 5)^2, or 12 = a(13/4)^2, or 1 = a(169/16).
Solving for a: a = 16/169 = 0.09, or approx 16/160, or 1/10. Unfortunately, this is not close to any of the four answer choices.
I thought it best to try again, and fortunately my second try was correct:
10+2 = a(13/4)^2, or (169/16)a. Thus, 12 = a(169/16)
12
Solving for a: a = ------------- = 1.14. The answer choice closest to this is 1.
169/16
Answer A is correct.
