Suppose analysts believe that this figure has increased recently, and they test their theory by randomly sampling 80 Americanhouseholds. Of the 80 households, 37% respond that they do use a computer or online financial program to manage their money. Is thisresult enough evidence to conclude that a significantly higher proportion of American households use a computer or online financialprogram to manage their money?

he North American Free Trade Agreement (NAFTA) enacted in 1994 is a trilateral trade agreement signed by the United States, Canada and Mexico. 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?

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%?

In order to estimate the proportion of students at a small liberal arts college who watch reality TV for more than 4 hours per week, a random sample of students at the school is selected and each is interviewed about his or her reality TV viewing habits. The students conducting the survey are worried that people that watch reality TV might be embarrassed to admit it and that they may not respond to the survey with honest answers. What type of bias are the students conducting the survey worried about? Measurement or response bias They shouldn't worry--there is no obvious source of bias. Selection bias Nonresponse bias
A research poll included 1614randomly selected adults who were asked whether "global warming is a problem that requires immediate government action." Results showed that 972 of those surveyed indicated that immediate government action is required. A news reporter wants to determine whether these survey results constitute strong evidence that the majority (more than 50%) of people believe that immediate government action is required. Complete parts (a) through (c) below. a. What is the best estimate of the proportion of adults who believe that immediate government action is required? the best estimate is ?
According to the IRS, individuals filing federal income tax returns prior to March 31 received an average refund of $1,078 in 2018 . Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). b. For a sample 400 of individuals who filed a tax return between April 10 and 15 , the sample mean refund was $920. Based on prior experience a population standard deviation of a=1,800 may be assumed. What is the p -value (to 4 decimals)? c. Using , can you conclude that the population mean refund for "last minute" filers is less than the population mean refund for early filers? yes or no d. Repeat the preceding hypothesis test using the critical value approach. Using a=0.05 what is the critical value for the test statistic (to 3 decimals)? Enter negative value as negative number. State the rejection rule: Reject if is the critical value. choices: greater than or equal to, greater…
Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 11.911.9 million out of the 312.7312.7 million Americans suffer from sleep apnea, or approximately 3.8%3.8%. A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population’s percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 3.8%3.8%, a simple random sample of 347347 commercial truck drivers is examined by a medical expert, who concludes that 66 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 3.8%3.8%? Use a 0.020.02 level of significance. Step 3 of 4 : Find the p-value.

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. If 5,128 U.S. adults were interviewed, what are the expected value of the number of people that answered that the justices should not bring their political views into decisions? What is the probability standard deviation in this case?
In a 2018 Poll 447 out of 486 supported universal background checks for all gun sales in the U.S. In a similar poll from 2015, 276 of 321 interviewed supported universal background checks. Is this significant evidence that the percent of the population that supports universal background checks in the U.S. has decreased during this time?
Sierra College students enrolled in an online Elementary Statistics course were asked to participate in an anonymous onlne survey. The survey asked the students "Which type of device will you primarily use to access your online course in Canvas?". Of the 152 students who answered this question, 20 responded "a desktop computer", 121 responded "a laptop computer", 6 responded "a smartphone", and 5 responded "a tablet". The Sierra College Mathematics Department believes that less than 5% of students enrolled in an online Elementary Statistics course primarily uses a smartphone to access their online course in Canvas. Use the data collected in the survey to conduct a hypothesis testing procedure to test this belief. What conclusion should be reached according to the results of this hypothesis test?
