To be able to tell the difference in cords
We can predict the hypothesis about the population proportion by determining the null and alternative hypotheses.
From the alternative hypothesis, you then determine the direction of the hypothesis test; which can be one-tailed or two-tailed.
For H0 , p=85.6% (The percentage of all undergraduate students enrolled in college and university in the United States is 85.6%).
Population proportion of success p=0.856.
A random sample of 489 enrolled college students in a particular state revealed that 438 of them were ungraduates.so,
Sample size n= 489
Number of success in the sample x = 438
sample proportion p= x/n = 438 / 489 = 0.895
Population proportion of failure q=1−p = 1- 0.895 = 0.105
putting all these values we can predict the proportion differs from the national percentage.

For southern producers, the war disrupted both the producing and the marketing of what they hoped would be the financial basis of their new nation. As Confederate territory shrank under Union attack, invasion, and occupation, the traditional patterns of cotton cultivation and sales likewise came under assault.
