Below is contingency table of 150 high school students at imaginary High School. The school wanted ta exolarestudeit pander with respect course level Honors Non-Honors Total Male 57 26 83 Female 40 27 67 Total 97 53 150 If the school wanted to investigate whether students in Non-Honors couses are more likely to be male or female Which conditional distribution Would they explore? A ) 69% Of Males are in Honors Courses versus 31% Non-Honors. B) 49% of Males are In Honors Courses versus 51% Non-Honors. C) 49% of Non-Honors are Male versus 51% Non-Honors courses are Female. D) 69% of Non-Honors are Male versus 31% Non-Honors courses are Female
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!
Below is
Honors Non-Honors Total
Male 57 26 83
Female 40 27 67
Total 97 53 150
