This question deals with a continuous uniform distribution between 50.0 and 52.0 minutes, and we need to find the probability that the class length is more than 51.2 minutes.

Solution

For a continuous uniform distribution $X$ between $a = 50.0$ and $b = 52.0$, the probability density function $f(x)$ is: $f(x) = \frac{1}{b - a} = \frac{1}{52.0 - 50.0} = \frac{1}{2}$

To find $P(X > 51.2)$, we calculate the area under the distribution curve from 51.2 to 52.0.

1. Calculate the range for $X > 51.2$: $P(X > 51.2) = \frac{b - 51.2}{b - a} = \frac{52.0 - 51.2}{2} = \frac{0.8}{2} = 0.4$

Answer

The probability that the class length is more than 51.2 minutes is: $P(X > 51.2) = 0.40$

Tip

In a continuous uniform distribution, the probability of any specific single point (like exactly 51.2 minutes) is always zero, as we are dealing with continuous data over an interval.
