Ahypothesis 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?

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.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

not sure but it may be b, as i said i'm not sure.
