<span>The Democrats harkened to the Jeffersonian ideal of an egalitarian agricultural society, advising that traditional farm life bred republican simplicity, while modernization threatened to create a politically powerful caste of rich aristocrats who threatened to subvert democracy. In general the Democrats enacted their policies at the national level, while the Whigs succeeded in passing modernization projects in most states.</span>
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.

Answer:
There were two main shortcomings with the Literary Digest's 1936 presidential poll:
- Sample bias: the magazine selected 10 million people out of three sources: telephone directories, club memberships, and magazine-suscriber lists. These sources gave the sample and middle an upper middle cass bias because in the epoch, few poor people owned telephones, were members of private clubs, or were suscribers of magazines.
- Nonresponse bias: Literary Digest wanted to survey 10 million people, but out of the 10 million people who received the poll, only 2.5 million people responded. This is called a nonresponse bias because the people who respond surveys have specific qualities different from the people who do not respond surveys.
Modern-pollsters tries to be more careful when selecting a sample: it should be representative of the population as a whole. Pollsters also have to deal with nonresponse bias, therefore, they try to send their surveys to people who are more likely to respond.
