Question 3On June 28, 2012 the U.S. Supreme Court upheld the much debated 2010 healthcare law, declaring itconstitutional. A Gallup poll released the day after this decision indicates that 46% of 1,012 Americansagree with this decision. At a 95% confidence level, this sample has a 3% margin of error.(b) How would you formulate a hypothesis test for the following claim "Majority of Americans think the2010 healthcare law is unconstitutional"? What is your null hypothesis? What is your alternativehypothesis? (Here "majority" means "more than 50%".)(c) What is the sampling distribution for X = nô under your null hypothesis?(d) Calculate p-value for the test problem in part (b) using the data based on the Gallup poll, based onthe sampling distribution in part (c).(e) How can you approximate the distribution of X under the null hypothesis using normal approximationto Binomial distribution? Draw the normal density curve and shade the area corresponding to yourp-value calculation (Hint: use pnorm or normTail).(f) Based on the p-value in part (d), what conclusion can you draw at significance level 0.01?

1) A Gallup poll asked a sample of Canadian adults if they thought the law should allow doctors to end the life of a patient who is in great pain and near death if the patient makes a request in writing. The poll included 260 people in Quebec, 163 of whom agreed that doctor-assisted suicide should be allowed. (a) What is the margin of error of the large-sample 96% confidence interval for the proportion of all Quebec adults who would allow doctor-assisted suicide? MoE: (b) How large a sample is needed to get a ±3 percentage point margin of error (this is very commonly used)? Use the previous sample as a pilot study to get p*. (You may need four decimal places in your critical value to solve this problem.) Sample size:
1) A 2010 survey asked 827 randomly sampled registered voters in California "Do you support? Or do you oppose? Drilling for oil and natural gas off the coast of California? Or do you not know enough to say?" Below is the distribution of responses, separated based on whether or not the respondent graduated from college. College Grad Yes No Support Oppose Do not know 154 132 180 126 104 131 Total 438 389 Conduct a hypothesis test to determine if the data provide strong evidence that the proportion of college graduates who do not have an opinion of this issue is different than that of non-college graduates. a) Write the hypotheses for this test.

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level.

A. μ = 321 B. p < 0.23 C. p = 0.23 D. μ < 321 Enter letter corresponding to correct answer (ii) Which of the following statements correctly defines the alternative hypothesis HA?

2. Toastmasters International cites a report by Gallup Poll that 40% of Americans fear public speaking. A student believes that less than 40% of students at her school fear public speaking. She randomly surveys 361 schoolmates and finds that 137 report they fear public speaking. Conduct a hypothesis test at the 5% level to determine if the percent at her school is less than 40%. a. State the null hypothesis. b. State the alternative hypothesis. c. Construct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.)
Members of the Town of Colonie Golfers’ Loop frequently raise concerns to Mr. Lange, as its leader, about how the league is run. The most frequent concern raised is that the teams competing each week are not statistically even. In other words, members raise concerns that one or more teams have a statistical advantage over other teams. To evaluate the validity of these claims, Mr. Lange has decided to use a mix of statistical hypothesis tests discussed in this course to evaluate the teams from Outing #14 in calendar-year 2016 (2016, #14). One is the Equal Vari- ances F Test, one is Welch’s T Test, and the other is the 2-Sample T Test for Equal Means. In this particular outing, seven teams were competing for the win. A random sample of eight prior scores from each team member was collected, and the summary statistics are shown below (correct to three decimal places). team sample size sample mean sample variance 1 24 76.500 14.522 2 32 79.656 18.233…
Suppose that in a recent poll, 550 of the 915 randomly selected U.S. adults agreed with the statement “social media sites like Facebook and Twitter do more to divide the country” (as opposed to unite the country, or neither). a. Use this information to construct a 90% confidence interval.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Confidence in banks: A poll conducted by the General Social Survey asked a random sample of 1325 adults in the United States how much confidence they had in banks and other financial institutions.
