A LA Fitness Manager wants to determine whether a LA Fitness member will lose weight after taking three months private gym classes. He selected 17 customers and measured their weights including the weights before the private gym classes (considered as group 1) and the weights after three months of private gym classes (considered as group 2). What is the degree of freedom

Respuesta :

Answer:

The degree of freedom = 16

Step-by-step explanation:

In conducting hypothesis tests where the population standard deviation isn't known, the t-distribution is used to obtain critical value and p-value of the distribution.

To use the t-distribution, the degree of freedom of the test is usually required.

The degree of freedom refers to the maximum number of independent variables, values or parameters, that are allowed to vary in the sample data.

The degree of freedom for a paired test with the same sample size for the two pairs, is given mathematically as

df = n - 1

where n = Sample size = 17

df = 17 - 1 = 16

Hope this Helps!!!
