A college student is doing some research on the cost of one-bedroom apartments in town. He has randomly selected 50 apartments for which the price was published. The average price for these apartments is x-bar = $652. A 95% confidence interval for u is found to be 652 ± 21.56 = ($630.44, $673.56). Determine which of the following statements is true A test of the hypotheses H_0: μ=675 vs. H_a:μ≠675 would be rejected at the 0.05 level. A test of the hypotheses H_0: μ=650 vs. H_a:μ>650 would be rejected at the 0.05 level. A test of the hypotheses H_0: μ=650 vs. H_a:μ≠650 would be rejected at the 0.05 level. All of these

A national opinion poll found that 44% of all American adults agree that parents should be given vouchers that can be applied toward their children's education at any public or private school of their choice. The result was based on a small sample. A)How large an SRS is required to obtain a margin of error of at most 0.03 in a 99% confidence interval? B) Answer the question in part A again but this time By using Phat=0.5. By how much do the two sample size differ?
On the Navajo Reservation, a random sample of 222 permanent dwellings in the Fort Defiance region showed that 56 were traditional Navajo hogans. In the Indian Wells region, a random sample of 141 permanent dwellings showed that 17 were traditional hogans. Let p1 be the population proportion of all traditional hogans in the Fort Defiance region, and let p2 be the population proportion of all traditional hogans in the Indian Wells region. Find a 90% confidence interval for p1 − p2. (Round your answer to three decimal places.) lower limit upper limit
A sample of size 25 was taken from a very large population. Sample statistics, x¯ and s, were used to find that the 95% confidence interval was (138.616, 163.384). x¯= s=
A random sample of 240 adults over the age of 40 found that 144 would use an online dating service. Another random sample of 234 adults age 40 and under showed that 131 would use an online dating service. Assuming all conditions are met, which of the following is the standard error for a 90 percent confidence interval to estimate the difference between the population proportions of adults within each age group who would use an online dating service?
A national poll asked, “how would you describe your job situation now compared to before the Covid-19 outbreak??” The results showed that 24% of workers in the U.S. report having a worse job situation now compared to before the COVID-19 outbreak began with a margin of error of 1.8%. (a) Assume the margin of error is reported for a 95% confidence interval, use this information to calculate a 95% confidence interval for the population proportion of persons who have a worse job situation now compared to before the outbreak. (b) Based on the calculated confidence interval, is there evidence that at least 1 out of every 4 (25%) Americans have a worse job situation not compared to before the outbreak? Explain why briefly. (c) What was the sample size of this poll? (d) If you wanted a 99% confidence interval for the same study, would your margin of error be greater than, equal to, or less than 1.8%?
The nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories and contains ten grams of fat, with three grams of saturated fat. A random sample of 35 bags yielded a conﬁdence interval for the number of calories per bag of 128.2 to 139.8 calories. Is there evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips? Group of answer choices A, None of the above answers is correct. Because 130 is inside the confidence interval, we have convincing evidence that the true average is any different than what the nutrition label suggests. Because 130 is inside the confidence interval, we know for certain that the true average is any different than what the nutrition label suggests. Because 130 is inside the confidence interval, we do not have convincing evidence that the true average is any different than what the nutrition label suggests.
An epidemiologist with the Florida Department of Health needs to estimate the proportion of Floridians who are infected with the corona virus but are asymptomatic (show no signs of the virus). The epidemiologist compiled a preliminary random sample of infected patients and found that 65% of the sample were also asymptomatic.How large a sample should be selected such that the margin of error of the estimate for a 96% confidence interval is at most 1.93%. Round the solution up to the nearest whole number.
From a random sample of 185 children from school G, 108 indicated they wanted to study science in college. From a different random sample of 165 children from school H, 92 indicated they wanted to study science in college. Assuming all conditions for inference are met, which of the following is closest to the standard error for a confidence interval for the difference in population proportions between the two schools of children who want to study science in college?
Based on sample data, the 95% confidence interval for the population mean is about $150 to $250. If the α = 0.05 level of significance was used in testing Ho: µ = $260 versus H1: µ ≠ $260, the null hypothesis. Would the null hypothesis be rejected or not?
In the past, 44% of those taking a public accounting qualifying exam have passed the exam on their first try. Lately, the availability of exam preparation books and tutoring sessions may have improved the likelihood of an individual’s passing on his or her first try. In a sample of 250 recent applicants, 130 passed on their first attempt. At the 0.025 level of significance, can we conclude that the proportion passing on the first try has increased? Construct a 95% confidence interval for π and using that interval, can you judge whether the proportion passing on the first try has increased?
A certain article indicates that in a sample of 1,000 dog owners, 620 said that they take more pictures of their dog than their significant others or friends. In addition, 470 said that they are more likely to complain to their dog than to a friend. Suppose that it is reasonable to consider this sample as representative of the population of dog owners. (a) Construct a 90% confidence interval for the proportion of dog owners who take more pictures of their dog than of their significant others or friends. (Round your answers to three decimal places.) ( , ) Interpret the interval choose one. a. We are 90% confident that the mean number of dog owners who take more pictures of their dog than of their significant others or friends falls within this interval. b. There is a 90% chance that the true proportion of dog owners who take more pictures of their dog than of their significant others or friends falls within this interval. c. There is a 90% chance…
