In hypothesis testing, A null hypothesis (H0) is a claim which the person conducting the research wants to test while an alternative hypothesis (H1) is a contradiction of the null hypothesis.
There are two types of tests in hypothesis testing.
One tailed test: In one tailed test, a claim that a parameter is greater than/ less than a value is being tested. i.e mean > value or mean < value.
Two tailed test: In a two tailed test, a claim that a value is equal to a value is tested, i.e mean = value.
In the question above, Colleen is testing the claim that the average score of her class is the same as others against that it is different from others.
Therefore, the null hypothesis is H0: mean = 514 while the alternative hypothesis is H1: mean ≠ 514

Answer:
LM > MK > KL
Step-by-step explanation:
Given: ΔKLM , m∠K = 101° , m∠L = 67°
By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°
By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.
Note the angles:
m∠M = 12° ∴ Side LK = shortest
m∠K = 101° ∴ Side ML = longest
m∠L = 67° ∴ Side KM = in between
∴ LK < KM < ML
A) LM > MK > KL is your answer.

Answer: I don't get the question, can you clarify?
Step-by-step explanation:
Answer: D) 
Step-by-step explanation:
From the given table we can see that this is not representing a linear function as the rate of change is not constant.
So it can be exponential growth function 
, where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.
Now here at n=1 , f(n)=8
Therefore, A=8
Now, for n=2
By substitute the values of A and b in the above equation, we get the equation
Therefore, the function best shows the relationship between n and f(n) is
, where n is the number of weeks.
