4. an organizational psychologist measures levels of job satisfaction in a sample of 30 participants. to
measure the variance of job satisfaction, it is calculated that the ss = 120 for this sample.
a. what are the degrees of freedom for the variance?
n= degrees of freedom (df): value - 1
the degrees of freedom of an estimate of variance is equal to n-1
the "n” refers to the number of observations
formula:
1) sample size of n = 30 / value or ss/n = variance
2) ss = 120/30 = 4 (df)
3) 30-1= 29 degrees of freedom

the answer is d

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
