Question A sample of 500 graduates was selected to determine their performance for government and private jobs. Of 300 males graduates, 210 preferred Government job white out of 200 female graduates, 130 preferred Government job. Is there any significance difference between male and female graduates as far as preference of job is concerned?
Answer Find the percentage of males and the percentage of females that are going to have government jobs. The variable p can be found by dividing 500 into 210+130. The variance is p(1-p)/n and is also the standard deviation squared.
Find the fraction of men and the fraction of women that are in governement jobs. Take the difference, divide by the standard deviation, and look up this number on a normal distribution table.
That will give you the probability of there being a difference in the men and women. It depends how much of a statistic significance you want as to whether there is one or not.
Thanks for your first question and I will gladly answer more.
