The principal at North High School is considering a schedule change to have lunch earlier in the day. If more than 50% of the student population supports changing the schedule, lunch will be moved to earlier in the day. The principal took a random sample of 100 students and found the 54 supported the change.  The principal conducts an appropriate significance test to see if there is convincing evidence that more than 50% of student population supports a schedule change to have lunch occur earlier in the day. Calculate the p-value for this test.

When playing the card game Blackjack, multiple decks are used and reshuffled often so that the outcomes of the cards dealt are approximately independent. When a player receives two cards that are a combination of an ace and a face card, this is called a “natural blackjack” and automatically wins. A natural blackjack should occur in 4.5% of the rounds played. What is the probability that a player plays 20 rounds of Blackjack and gets three or more natural blackjacks?

According to the National Association of Colleges and Employers, the mean salary for a new college graduate is $45,327. A small college wants to know if the mean salary of their most recent graduates is greater than $45,327. A random sample of 10 recent graduates from the small college was selected and the mean and standard deviation of the salary for those graduates was found. With all conditions for inference met, a test statistic of 2.51 was calculated. What is the p-value for the test?
