A statistician claims that the proportion of students who will vote for Mr. K to be the next president is 0.54 with the standard deviation of 0.3.

Identify the hypothesis test
If 1000 students are randomly selected and 455 of them will not vote for Mr. K, what is the P-value? What can you conclude based on 5% significant level?
Construct a 95% Confidence Interval
If Mr. K is ended up losing the election, does this make sense? Why or why not?

An FM rock station claims that 85% of all its listeners are college students. A statistician decides to test this claim against the suspicion that the percentage is too high. A random sample of 2000 listeners is selected from the population of all listeners and it is determined that 1655 are college students. Perform a hypothesis test to answer the question: Do the sample results support the statistician’s claim at α = 1 %? I. State the hypotheses (in words...

A political science professor is interested in comparing students who do and do not vote in federal elections. She computes the mean grade point average for a random sample of 14 students who have voted in the last federal election to be 2.51 with a standard deviation of 0.44. She computes the mean grade point average for a random sample of 15 students who did not vote in the last election to be 2.98 with a standard deviation of 0.56....

The dean of the school wants to know the proportion of students in the school who prefer online classes for the next semester. How do you conduct a research to estimate this proportion by sampling (suppose that you can take only one sample of size n which is smaller than the population size N, and also suppose that a %90 percent confidence interval is fine). - You should explain all steps you take including how you make decision about sample...
