A university pays an average of Php 425.00 per hour of work to their faculty members, with a standard deviation of Php 50.00. Assuming that the payment is normally distributed, draw the corresponding normal curve and compute the probability that an employee’s hourly rate is greater than Php 504.00. between Php 362.00 and Php 442.00. less than Php 480.00.
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!
A university pays an average of Php 425.00 per hour of work to their faculty members, with a standard deviation of Php 50.00. Assuming that the payment is
- greater than Php 504.00.
- between Php 362.00 and Php 442.00.
- less than Php 480.00.
- greater than Php 382.50.
- between Php 475.00 and Php 535.00.
- less than Php 404.00.
