who can answer any of these

find each of the following probabilities for a normal distribution:

a. p(z>-1.00)

b. p(z>-0.80)

c. p(z<0.25)

d. p(z<1.25)

for a normal distribution idenitfy the z-score location that would seperate the distriubtion into two sections so there is:

a. 70% in the body on the right-hand side.

b. 80% in the body on the right-hand side.

c. 75% in the body on the left-hand side.

d. 90% in the body on the left-hand side.

information from the dmv induicates the average of licensed drivers is mean- 39.7 and standard deviation of o- 12.5 years. assume that the distriubtion of drivers age is approx. normal.

a. x=85

b.x= 92

c. x=78

d. x=72
