Answer:
Step-by-step explanation:
We know that normal distribution as special characteristics such as symmetry, unimodal, no skewness, mean =median=mode, etc
A standardized variable for normal variable X is
will be normal with mean =0 and sigma =1
The probability will be divided equally on either side of the mean =0 i.e. y axis
Hence the answers would be
A standardized variable always has a mean of __0_____ and a standard deviation of ___1____. b. The z-score corresponding to an observed value of a variable tells you ____the std normal score.___. c. A positive z-score indicates that the observation is __to the right ____ the mean, whereas a negative z-score indicates that the observation is __to the left_____ the mean
Question:
Solution:
Note that if we evaluate x = -1, 0, and x=1 in the last equation we get:
y = 3(-1)+ 3 = -3+3 = 0
y = 3(0)+3 = 3
y = 3(1)+3 = 6
So that, we can conclude that the correct solution is
D. y =3x + 3
