Question 2 of 9 (i point) A sample of size 190 will be drawn from a population with mean 45 and standard deviation 11. Use the TI-84 calculator. Part 1 of 2 Find the probability that x will be less than 43. Round the answer to at least four decimal places. The probability that x will be less than 43 is Part 2 of 2 Find the 60" percentile of x. Round the answer to two decimal places. th The 60 percentile is
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!
