B, X is any number greater than or equal to 19.
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.
The difference of two squares. The number which, when multiplied together three times yields the original number.
Answer: 56
Step-by-step explanation:
Given : A bag contains five red marbles, three green ones, one transparent one, three yellow ones, and three orange ones .
Red marbles = 5
Green marbles = 3
Total marbles red or green = 5+3=8
The number of combinations of n things taking r at a time is given by :-
Then, the number of possible sets of five marbles are there in which all of them red or green is given by :-
Now, the number of possible sets of five marbles are there in which all of them red or green = 56
