    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.
