Given that z is a standard normal random variable, find z for each situation.
cestrela7 [59]
You have to use your standard normal table (or calculator) for these. The area under the curve should be 1, a z-value corresponds to the probability and is area to the left of that z.

a. A simple reverse lookup of 0.9750. z=1.96

b. Total area up to z would be 0.5+0.4750, so reverse look up 0.9750 and find z=1.96

c. A simple reverse lookup. z=0.61

d. Area to the left of z would b 1-0.1314, so lookup 0.8686 and find z=1.12

e. A simple reverse lookup. z=0.44

f. Just invert the area: 1-0.33 = 0.67 and reverse lookup: z=0.44

Barry Allen's older brother is only 3 years more than triple Barry's age. If the sum of their ages is 28, find their ages
Sloan [31]
B and a
barry=b
a=older bro

a is 3 more than 3b
a=3+3b
sum is 28
a+b=28
3+3b+b=28
3+4b=28
minus 3 both sides
4b=25
divide both sides by 4
b=6.25

a=3+3b
a=3+3(6.25)
a=3+18.75
a=21.75


barry=6.25 years
21.75 years=older bro
