Answer:
c. you reject a null hypothesis that is true
Step-by-step explanation:
We need to remember the following concepts
Error type I: Is an error associated to the probability of reject a null hypothesis when it is actually true
Error type II: Is an error associated of not rejecting a null hypothesis when the alternative hypothesis is the true
And the best answer for this case would be:
c. you reject a null hypothesis that is true
Answer:
b = 6
Step-by-step explanation:
You probably already know the general equation from the my last couple of answer.
In this question, we have:
a=8
b= ?
c= -10 , c is the value of the foci
surprisingly, you can solve the value for a, b, and c using the same equation as the Pythagorean theorem.
c² = a² + b²
we need to solve for b so lets rearrange the equation.
b² = c² - a²
b = ±√(c² - a²)
b = ±√((-10)² - (8)²)
b = ±√((-10)² - (8)²)
b = ±√(100 - 64)
b = ±√(36)
b = ±6
b = 6
In 9, the error is that the 276 should be the numerator, not the denominator, because in the proportion Elisa made, the number of students is the numerator and the number of teachers is the denominator.
