Answer:


Step-by-step explanation:
We know that the null hypothesis is the statement which show that there is no statistical difference between two groups tested.
The alternative hypothesis is the statement which is exactly opposite to the null hypothesis . i.e. it shows that there is statistical difference.
According to the given question, we have
Null hypothesis : 
Alternative hypothesis : 
Hence, the appropriate hypotheses for this test :


Theoretical probably is what you would expect to happen.
Example, flipping a coin has a 50% chance of landing on heads, so if you flipped a coin 100 times, theoretically the coin would land on heads 50 times ( 50%).
Experimental probablity is what actually happens. Using the coin example, flipping the coin 100 times, it could actually land on heads 100 times or any number of times from 0 to 100.
A digit in the ten thousand place is 10x times larger than a digit in the thousands place.
We can see that here- 1,000 x 10 = 10,000
The answer is: 30 goodluck!!!!!!!!!!!!!!!!!!!!!!!!!!
