Answer:
Black is 3.57%
Green is 96.43%
Step-by-step explanation:
Since 27 green than black
Let the black car be b
So green cars which 27 more than black means 27b
So to calculate the percentage of green we will have
27b/27b+b ×100
27b/28b ×100
Let's eliminate the b
27/28×100
2700/28
96.43%
So let's calculate for Black
b/27b+b ×100
b/28b ×100
Eliminate b
1/28 ×100
100/28
3.57%
Therefore the percentage for Black is 3.57% and for green is 96.43%
You'll need to calculate the applicable z-score:
(given value of x) - (mean value)
z = -----------------------------------------------
standard deviation
370-400 -30
Here, z = --------------- = ---------- = -0.3
100 100
Use either a table of z scores or your calculator to determine the area under the standard normal curve to the left of z = -0.3.
According to my TI-83 Plus calculator, this area is 0.382.
The probability of selecting at random a score less than or equal to 370 is 0.382.
