I'm not being able to identify the mathematical pattern used answer this question:
Suppose that the length of a speficic kind of snake may be modelled by a normal distribution with mean 50.8 (cm) and standard deviation 0.8.
Calculate the length (cm) that is exceeded by only 7% of this specific kind of snake.
What I though:
- Plot the C.D.F and find the 93th percentile (maybe using z-score)?. is that correct?
