Answer:
0.081,0.2621,0.645,0.919
Step-by-step explanation:
Let X be the average speed of a car driving down freeway
Given that X is normal with mean as 70mph with a standard deviation of 5mph.
To convert to Z score we do
a) the probability that a randomly selected car is driving more than 77mph
b) probability that a randomly selected car is driving between 65 and 69 mph
=
c) the probability that a randonly selected car is driving between 67 and 77mph
=
d) the probability that a randomly selected car is driving less than 77mph
The solution to the problem is as follows:
<span>Write the decimal number as a fraction
(over 1)
0.336 = 0.336 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator (N)
N = 0.336 × 10 × 10 × 10 = 336
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000
N / D = 336 / 1000
Simplifying our fraction
= 336/1000
= 42/125</span>
