Answer:
16/9
Step-by-step explanation:
(4/3) ^2
(4/3) * (4/3)
First the numerators
4*4 = 16
Then the denominators
3*3 = 9
Numerator over denominator
16/9
Answer:
2 , 3
Step-by-step explanation:
Answer:
C. The degree of dependence among the observation is negligible.
Step-by-step explanation:
The conditions for performing a t-procedure when constructing a t-interval are;
1) The samples observation should be independent of each other
2) The use of a random sample or experiment for the procedure
3) Ensure the normality of the data of the dependent variable
Given that surveys usually involve sampling without replacement from a population which is finite can not be taken as independent Bernoulli trials however, it is allowable to still consider samples independent when they are less than 10% the size of population
Therefore, the reason for the condition is to ensure that the population to sample size ratio is large enough and that the degree of dependence among the observation is negligible.
By the triangle inequality theorem we know that
b - a < c < a+b
where a and b are the given sides; c is the unknown side
In this case,
a = 12
b = 13
c = n
So,
b-a < n < b+a
13-12 < n < 13+12
1 < n < 25
So n is both greater than 1 and also less than 25
Broken up, this means n > 1 and n < 25
So it looks like the only answer is choice A. Choices C and D seem to have typos in them? Something seems off about them.
