If the mean body tempe tire of a bird is 75 degrees with a standard deviation of 4 degrees, which is least likely? 1. A random sample of 50 birds will have a mean body temperate that is less than 72 degrees 2. a single bird, chosen at random, has a body temperature that is less than 72 degrees. 3. a random sample of 10 birds will have a mean body temperature less than 72 degrees. I know it isn't #2. Please explains steps on how you solved!
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!
