Answer:
Null Hypothesis, :
= 2.0 units or
= 2.0 units
Alternate Hypothesis, :
2.0 units or
2.0 units
Step-by-step explanation:
We are given the following data below and we have test if the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2;
Pair : 1 2 3 4 5 6 7
Sample1 : 5 6 10 3 6 7 8
Sample2 : 4 4 3 5 5 5 3
Let = population mean represented by Sample 1
= population mean represented by Sample 2
= population mean matched-pair differences for Sample 1 - Sample 2
So, Null Hypothesis, :
= 2.0 units or
= 2.0 units
Alternate Hypothesis, :
2.0 units or
2.0 units
Here null hypothesis states that the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2.
On the other hand, alternate hypothesis states that the population represented by Sample 1 has a mean that is not 2.0 units higher than the population represented by Sample 2.
