- According to a report on consumer fraud and identity theft, 26% of all complaints for a year were for identity theft. In that year, Missouri had 938 complaints of identity theft out of 3400 consumer complaints. Does this data provide enough evidence to show that Missouri had a different proportion of identity theft than 26%? Test at the 10% level. State the hypotheses.

This trade agreement has been controversial since its inception and Americans remain split on the issue. In a Gallup Poll conducted February 1-5, 2017, 420 out of 912 randomly selected Americans aged 18 or older stated that they believed that NAFTA was bad for the United States. Find the point estimate for the proportion of Americans who believe that NAFTA was bad for the United States. Round your answer to 4 decimal places. Find the margin of error for a 95% confidence interval. Round your answer to 4 decimal places. Construct the 95% confidence interval for the proportion of Americans who believe that NAFTA was bad for the United States. Enter your answer as an open interval of the form (a,b) and round to 3 decimal places. Can you conclude that more than half of Americans believe that NAFTA was bad for the United States? No conclusions can…Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May 19, 2018).

- A friend of yours tells you that they heard that 65% of all college athletes end up losing a finger or toe in their college athletic career. You're highly skeptical of this, but your not sure if that percentage is an over exageration or an under exageration. You survey 101 former student-athletes and find that 60 of them lost a digit during their college athletic career. Is this enough evidence to conclude that the true percentage of student-athletes that lose a digit during their collegiate career is really different from 65%?According to a report on consumer fraud and identity theft, 24% of all complaints for a year were for identity theft.

- 7.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.A Pew Research Center report published on February 2, 2022 says, “In a national survey by Pew Research Center, 54% of U.S. adults say they have a favorable opinion of the Supreme Court while 44% have an unfavorable view, and 84% say justices should not bring their political views into decisions.” Answer the given problems based on the assumption that the above figures represent the true proportion of current U.S. people’s opinion. 4.1. If 20 U.S. adults are selected at random, what is the probability that less than half the selected people have favorable view on U.S. Supreme Court? 4.2. If 20 U.S. adults are selected at random, what is the probability that more than half the selected people have unfavorable view on U.S. Supreme Court? 4.3.
