Answer:
Statistical significance relates to whether an effect exists.
Practical significance refers to the magnitude of the effect.
And you can have statistical significance but not practical.
Step-by-step explanation:
Let's analize it with an example.
Suppose that your new treatment involves hair recovery.
You divide the population of the test in two different groups.
And you apply the treatment to only one of them.
You can see that the treatment works and there is a 3% improvment.
You have statistical significance. The treatment worked.
Now, if the test was expensive, the 3% improvement might not be practical.

Answer:
Step-by-step explanation:
Find the slope by doing rise/run
-2/3
Find the y intercept: (0, -2)
The equation will be y = -
x - 2
Answer:4) 1.05(0.85y)
Step-by-step explanation:
take off 15% from y which will leave you with 85% left -> (0.85y)
then you have to find 5% from the discounted price and add it to the original price 1.05(8.5y) the 1 will give you your original price while the .05 will add on your tax.
