Answer:
 
Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have  and for the denominator we have
 and for the denominator we have  and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:
 and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:
 
For this case the p value is highert than the significance level so we haev enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviations are not significantly different
Step-by-step explanation:
Information given
 represent the sampe size 1
 represent the sampe size 1
 represent the sample 2
 represent the sample 2
 represent the sample deviation for 1
 represent the sample deviation for 1
 represent the sample variance for 2
 represent the sample variance for 2
 represent the significance level provided
 represent the significance level provided
The statistic is given by:
 
Hypothesis to test
We want to test if the variations in terms of the variance are equal, so the system of hypothesis are:
H0:  
H1:  
The statistic is given by:

Step-by-step explanation:
6+6=12
As, 6 x 2 = 12
An example = 6 books were in ur classmates desk, and u had 6 book as well in ur desk
U wanted to build a tower of books
So merged them together 
And put them on each other until all books are done
Which now u will simply add the 6 books of ur classmate and urs 
Which will be 12 book

Answer:
Hello your question has a disjointed equation attached to it and it is also incomplete attached below is the correct and complete question
A teacher believes that the third homework assignment is a key predictor in how well students will do on the midterm. Let x represent the third homework score and y the midterm exam score. A random sample of last terms students were selected and their grades are shown below
answer : 
y-intercept = 25.9047
  slope = 2.8420
Step-by-step explanation:
Determine the slope for the regression equation and y intercept 
The regression equation ( gotten using excel ; attached below is the excel sample on how the equation was gotten ) 
 y = 25.9047 + 2.8420x
from the equation gotten above 
y-intercept = 25.9047
slope = 2.8420
