Answer:
The p value on this case is given by the problem.
If we compare the p value with a significance level assumed , we see that
and we can conclude that we FAIL to reject the null hypothesis that the difference mean between after and before is less or equal than 0.
Step-by-step explanation:
A paired t-test is used to compare two population means where you have two samples in which observations in one sample can be paired with observations in the other sample. For example if we have Before-and-after observations (This problem) we can use it.
Let put some notation
x=test value before , y = test value after
The system of hypothesis for this case are:
Null hypothesis:
Alternative hypothesis:
The first step is calculate the difference
The second step is calculate the mean difference
The third step would be calculate the standard deviation for the differences, and we got:
The 4 step is calculate the statistic given by :
The next step is calculate the degrees of freedom given by:
Now we can calculate the p value, since we have a right tailed test the p value is given by:
The p value on this case is given by the problem.
If we compare the p value with a significance level assumed , we see that
and we can conclude that we FAIL to reject the null hypothesis that the difference mean between after and before is less or equal than 0.
Answer:
Linear Function
Step-by-step explanation:
Given
The table showing values of x and y
Required
Determine the type of function
To determine the type of function, the table represents;
One will need to determine the table equation.
Start by solving for the slope;
When x - 0; y = 0 and When x = 80; y = 60.
This gives
The formula is determine as follows;
When x - 0; y = 0; m = 3/4; This gives
Open Bracket
The above is an example of a linear equation.
<em>Hence; option B answers the question</em>
