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

Find the probability that an individual’s blood clotting time will be less than 2 seconds or greater than 13 seconds:

Consider the variable clotting time of blood as X.

The assumption is made that the variable clotting time of blood X is normally distributed.

Here, the mean of blood clotting time is μ = 7.45 seconds and standard deviation is σ = 3.6 seconds.
