Answer:
DF = 458
Step-by-step explanation:
In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.
The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;
DF = n - 1
where n is the sample size
Given n is 459, DF = 459 - 1 = 458
Therefore, DF = 458
48 Is the answer that should be removed !
The greatest common factor would be 16
Answer:
Step-by-step explanation:
Slope = (y2 -y1)/(x2-x1)
y2 = 800, y1 = 400, x2= 4, x1= 2
Slope = (800-400)/(4-2)
= 400/2
= 200calories/hr
Yes u have to and as long are you do than you would be right
