The baking time for a cake is uniformly distributed between

The baking time for a cake is uniformly distributed between 16 and 22 minutes. What is the probability that on a given day, the product will take more than 18.6 minutes?

Solution

Mean = 19
Standard Deviation SD =4.24

z = (X-Mean)/SD
= (18.6 - 19)/4.24
= -0.094

P-value = 1 - 0.4641 = 0.5359 Answer
