### Survey Analysis of Favorite and Least Favorite School SubjectsIn a survey involving 1,000 randomly selected adults in the United States, participants were asked to identify their most and least favorite subjects during their school years (Associated Press, August 17, 2005). In an interesting twist, mathematics was the subject most frequently chosen in both categories. Specifically, 222 out of the 1,000 participants selected math as their favorite subject, while 362 identified it as their least favorite.#### Statistical Task(a) **Construct a 95% Confidence Interval for the Proportion of U.S. Adults for Whom Math Was the Favorite Subject in School.**- Provide the interval answers to three decimal places.(b) **Construct a 95% Confidence Interval for the Proportion of U.S. Adults for Whom Math Was the Least Favorite Subject.**- Provide the interval answers to three decimal places.#### ActionTo proceed further with this analysis, click on the "USE SALT" button. This may provide additional tools or options for completing the tasks outlined above.

A teacher wants to interview a random sample of 6 students from their class of 25 students. How many samples (or groups) of 6 students can the teacher interview? Is this a combination or permutation? How many different possible samples are there?
A researcher studies the effects of guilt on memory. First, subjects perform a very boring task for one hour. Then each subject is instructed to tell the next subject either (a) that the experiment took one hour and they found it very boring, or (b) that the experiment took one hour and was very interesting. After that, each subject is asked to study a list of words and are tested on memory for the list. 30 subjects are randomly assigned to one of the two conditions. In order to see whether the experimental manipulation has any effect on memory, which would be the proper statistical test? A)a related sample t-test-test   B)an independent sample t-test   C)a z test   D)a one sample t
g) The Lady Tasting Tea Experiment. An English lady, Muriel Bristol, claimed that she can tell whether tea or milk was added first to a cup. So as a researcher, you want to test whether she can really tell whether tea or milk was added first. But how would you do it? A possible research design: Give her eight cups, four where tea is added first and the other four where milk is added first, in random order. Then ask her to pick out the four cups where the milk is added first. After you conducted the experiment and collected the data, how do you decide whether she can truly tell the difference or she was just guessing. Our intuition tells us that the more cups she gets correctly, the more likely that she is NOT guessing. "If the Lady is just guessing, the probability of getting it all correctly is 1.4%." Now using your knowledge on combinatorics and probability, explain how this number was calculated? h) Suppose you flip four fair coins. What is the probability that you will get all…

Med School 2011 According to the Association ofAmerican Medical Colleges, only 46% of medical schoolapplicants were admitted to a medical school in the fallof 2011.5Upon hearing this, the trustees of StrivingCollege expressed concern that only 77 of the 180students in their class of 2011 who applied to medicalschool were admitted. The college president assured the trustees that this was just the kind of year-to-year fluctua-tion in fortunes that is to be expected and that, in fact, the school’s success rate was consistent with the nationalaverage. Who is right?a) What are the hypotheses?b) Check the conditions and find the P-value.c) Are the trustees right to be concerned, or is thepresident correct? Explain.
You want to study whether music affects people’s ability to learn. You have 10 college students study a list of words with soft classical music playing, then you test how many words they correctly remember. You have 15 different college students study a list of words with loud heavy metal playing, then you test how many words they correctly remember. You want to compare the learning/memory of the two different groups. What kind of hypothesis test should you do? One-Sample z-test One-Sample t-test Independent-Samples t-test Related-Samples t-test
