Answer:
Null hypothesis:
Alternative hypothesis:
Step-by-step explanation:
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
On this case the claim that we are trying to proof is "A movie streaming company only holds on to a movie in its offering if the movie has had a 4.5 rating or above". So that needs to be on the alternative hypothesis. And the complement should be the null hypothesis.
Null hypothesis:
Alternative hypothesis:
We have another into to complete the test for example:
represent the sample size selected
The value that we want to test
represent the significance level
Confidence =95% or 0.95

Step-by-step explanation:
Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as
1070=180(n-2) where n is the number of sides required here.
Making n the subject of the formula then following step by step
Therefore, the shape is octagon and it has 8 sides.
The correct answer is C because it is reflected over the y axis
