Question

A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. What is the degree of freedom?

Answer 1

Answer:

Degree of freedom is 6.

Step-by-step explanation:

A sample of seven infants is randomly selected and their weights at birth are recorded.

Given, Population mean = 6.6 pounds

Sample size = n = 7

Degree of freedom = n - 1

                                = 7 - 1

                                = 6

Degree of freedom is 6.
