In a recent Super Bowl, a TV network predicted that 54 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 81 people who saw the commercials and found that 46 of them said they would watch one of the television shows.

- A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 69% . Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0:H1:=The College Board reported that 58.7% of all students who took the 2010 AP Statistics exam earned scores of 3 or higher. One teacher wondered if the performance of her school was better. She believed that year's students to be typical of those who will take AP Stats at that school and was pleased when 34 of her 54 students achieved scores of 3 or better. Ca she clain that her school is better? To verify her clain, test the following hypotheses at Alpha =5%. Ho:P = 0.587 vs Ho:P>0.587At a high school debate tournament, half of the teams were asked to wear suits and ties and the rest were asked to wear jeans and T-shirts. The results are given in the table below. In order to test the claim at the 0.05 level that the proportion of wins is the same for teams wearing suits as for teams wearing jeans, what would the null hypothesis be? Win Loss Suit 22 28 T-Shirt 28 22 O A. The proportions of wins is different for teams wearing suits as for teams wearing jeans. O B. The proportions of wins is the same for teams wearing suits as for teams wearing jeans. O C. The mean number of wins is the same for teams wearing suits as for teams wearing jeans. O D. The mean number of wins is different for teams wearing suits as for teams wearing jeans.
- A recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percentage. Suppose that a survey of 100 local seniors and 100 national seniors is conducted to see if the proportion of drug and alcohol use is higher locally than nationally. Locally, 65 seniors reported using drugs or alcohol within the past month, while 60 national seniors reported using them. Conduct a hypothesis test at the 5% level.NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) Part (a) State the null hypothesis. H0: plocal ≠ pnational H0: plocal > pnational H0: plocal = pnational H0: plocal < pnational Part (b) State the alternative hypothesis.

- A statistics professor wants to see if more than 80% of her students enjoyed her class. At the end of the term, she takes a random sample of students from her large class and asks, in an anonymous survey, if the students enjoyed taking her class. A p-value of o.12 in this problem indicates.. A 12% of students in teh sample enjoyed the class. there's a 12% chance that under 80% of all students enjoyed the olass. C there's a 12% chance that over 80% of all students enjoyed the class.

Specifically, he believes that male dogs are better at relieving anxiety compared to female dogs. The head of the BCIE (Dr. Wolf) is not really convinced. She believes that the secret to relieving anxiety lies with the age of the dog. Together they devise an experiment to test this hypothesis. Specifically, they assign 28 participants to one of four therapy groups (male puppy, male senior dog, female puppy, female senior dog) for one week. At the end of the week, they measure the anxiety level of participants on a scale that ranges from 1 to 10 (with higher scores indicating more anxiety). The table below presents the data from their study. Please help the researchers solve the different steps in this factorial ANOVA. I have provided you with the formulas for a between groups factorial ANOVA and you need to fill in the 24 blanks to calculate SSage, SSgender.…In a recent Super Bowl, a TV network predicted that 59 % of the audience would express an interest in seeing one of its forthcoming television shows.
