Answer:
Alternate Hypothesis: The true weight of the piglets is greater than or equal to 39 lbs.
Step-by-step explanation:
Hypothesis testing is more like a binary process in which only one (Either Null or Alternate Hypothesis can be true) and we have to infer that whether our Null hypothesis is true or false.
The hypothesis testing involves following 4 general steps:
- State the 2 hypothesis by making sure that they don't overlap with each other
- Develop the analysis plan or any statistical method to know whether the Null hypothesis should be accepted or rejected
- Execute the developed plan and analyze the data
- In the end, after analyzing the data accept or reject the null hypothesis
As in the given question, if a number (X) is less than another number (Y) then it can't be less, equal or greater simultaneously.
Answer:
x=2

Answer:
99% confidence interval is:
(0.00278 < P1 - P2< 0.15921)
Step-by-step explanation:
For calculating a confidence intervale for the difference between the proportions of workers in the two cities, we calculate the following:
Where : proportion sample of individuals who worked
at more than one job in the city one
: Number of respondents in the city one
: proportion sample of individuals who worked
at more than one job in the city two
: Number of respondents in the city two
Then
α = 0.01 and α/2 = 0.005
and
and
The confidence interval is:
(0.00278 < P1 - P2< 0.15921)
Answer:
C
Step-by-step explanation:
Triangles will only be right triangles if a² + b² = c² where a and b are legs and c is hypotenuse. Numbers 1 and 2 pass this test so the answer is c.
