Small newborn seal pups have a lower chance of survivl. Suposse that the length of a newborn seal pup is a normal distribution with a mean length of 29.5 inches and a standard deviation of 1.2 inches. A. What is the probability that a newborn pup selected at random will be between 27 and 31 inches long? Include a sketch in answer. Rounding rule for probability: 3 decimal places B.Draw a sketch, then find the seal pup length that represents P80, the 80th percentile. Include units answer. Rounding rule:3 decimal places C. What would be the minimum length of sealpups in the top 2%, the very largest of them? Include a sketch and units in answer. Rounding rule: 3 decimal places
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
