Question

12. Consider the normal curves that have the parameters $μ = 1.5$ and $σ = 3; μ = 1.5$ and $σ = 6.2; μ = - 2.7$ and $σ = 3; μ = 0$ and $σ = 1 .$
a. Which curve has the largest spread?
b. Which curves are centered at the same place?
c. Which curves have the same spread?
d. Which curve is centered farthest to the left?
e. Which curve is the standard normal curve? $σ$

Accepted Answer

a. The curve which has the largest spread parameter is $μ = 1.5$ and $σ = 6.2$

b. The curves which are centered at the same place is $μ = 1.5$ and $σ = 3$ and $μ = 1.5$ and $σ = 6.2 .$

c. The curves which have the same spread is $μ = 1.5$ and $σ = 3$ and $μ = - 2.7$ and $σ = 3 .$

d. The curve which is centered farthest to the left is $μ = - 2.7$ and $σ = 3$

e. The curve which is the standard normal curve is $μ = 0$ and $σ = 1$
