I can’t calculate the mean of this data set without a data set
Answer:
a) D. The group of all of the babies whose recorded weights were examined
b) A. The weights of the babies at birth
c) i) Ux' = u = 3370;
s.d = 43.95
ii) Ux' = u = 3370
s.d = 35.109
Step-by-step explanation:
Given:
Mean, u = 3370
Standard deviation = 582
a) Population in statistics involves every member of the group in study.
Here, the correct population is the group of all of the babies whose recorded weights were examined.
b) In statistics, variable involves data collected.
The correct variable is the weights of the babies at birth
c)
i) at X' = 175
Sample mean:
Ux' = u = 3370
Standard deviation:
ii) at X' = 175
Sample mean:
Ux' = u = 3370
Stanard deviation:
Y(3y-4)
The y can be factored out of both equations
The answer is 3x - y = -7 (if you put both sets of coordinates in the place of x and y you get -7)
For example: 3•(-2) - 1 = -7
