Question

A recent study showed that the length of time that juries deliberate on the verdict for civil trials is normally distributed with a mean equal to 15.56 hours with a standard deviation of 3.7 hours. Give this information, what is the probability that a deliberation will last more than 22 hours?

Answer 1

$$p=F(t)$$

$$t=\frac{22-15.56}{3.7}=1.74$$

$$p=0.4591$$
