Question

A new hybrid was recently introduced to the market distance trouble on 1 L of fuel is normally distributed with a mean of 28 km and a standard deviation of 2 km find the probability that a car will travel more than 31.16 km one litre of fuel

Expert Solution
Step 1

Here it is given that-

Mean (μ) = 28

Standard deviation (σ) = 2

Let X be a random variable which denotes the distance travelled by hybrid. X follows normal distribution.

~N(28,22)

So,

Z = X-282~N(0,1)
