Question

Asked Apr 3, 2019

The mean clotting time of blood is 7.45 seconds with a standard deviation of 3.6 seconds. What is the probability that an individual's clotting time will be less than 2 seconds or greater than 13 seconds? Assume a normal distribution.

The probability is?

Step 1

**The normal distribution:**

A continuous random variable *X* is said to follow normal distribution if the probability density function of *X* is,

Step 2

**Computing the probability that an individual’s clotting time will be less than 2 seconds or greater than 13 seconds is given below:**

Here, the random variable *X* , the clotting time of blood is normally distributed with mean *μ* = 7.45 seconds, standard deviation, *σ* = 3.6 seconds. The probability that an individual’s clotting time will be less than 2 seconds or greater than 13 seconds can be obtained as follows:

Step 3

Thus, the probability that an individual’s clotting time will ...
