A college recently advertised that 92% of its students graduate debt-free.A student advocacy organization thinks that the college's claim is unlikely. The organization collected arandom sample of 1051 recent graduates from the college and found that 90.2% of the sample graduatedwithout any student debt.Use significance level of 10 % and employ the critical-vproportion of all students from this college that graduate debt-free is different than 92%.method to test the hypothesis that theState the null and alternative hypothesis for this test.О Н: р < 0.92, Н:р > 0.92О Но:р - 0.92, Ні:р 40.92О Но:р 4 0.92, H:р - 0.92О Но:р > 0.92, Нi:р <0.92Determine the critical-value (s) for the hypothesis test.O-1.96, 1.96O-1.64, 1.64O-2.81, 2.8101.64Determine test statistic for the hypothesis test.O 3.38 O1.64Determine test statistic for the hypothesis test.O-3.38O 4.21O 2.99O-2.15Determine the appropriate conclusion for this hypothesis test.O The sample data do not provide sufficient evidence to reject the alternative hypothesis that theproportion of all students at the college that graduate debt-free is different than 0.92 and thus weconclude that the proportion of all students at the college that graduate debt-free is likely differentthan 0.92.O The sample data provide sufficient evidence to reject the alternative hypothesis that the proportionof all students at the college that graduate debt-free is different than 0.92 and thus we concludethat the proportion of all students at the college that graduate debt-free is likely equal to 0.92.O The sample data do not provide sufficient evidence to reject the null hypothesis that the proportionof all students at the college that graduate debt-free is 0.92 and thus we conclude that theproportion of all students at the college that graduate debt-free is likely equal to 0.92.O The sample data provide sufficient evidence to reject the null hypothesis that the proportion of allstudents at the college that graduate debt-free is 0.92 and thus we conclude that the proportion ofall students at the college that graduate debt-free is likely different than 0.92.

In a study of 420,141 cell phone users, 134 subjects developed cancer of the brain or nervous system. Test the claim of a somewhat common belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.001 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. Which of the following is the hypothesis test to be conducted? Ho: p 0.00034 D. Ho: p0.00034 H₁: p = 0.00034 F. Ho: p > 0.00034 H₁: p = 0.00034
A random sample of n1 = 299 voters registered in the state of California showed that 140 voted in the last general election. A random sample of n2 = 220registered voters in the state of Colorado showed that 130 voted in the most recent general election. Do these data indicate that the population proportion of voter turnout in Colorado is higher than that in California? Use a 10% level of significance. What is the level of significance? What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.) Find (or estimate) the P-value. (Round your answer to four decimal places.)
US Universities found that 72% of people are concerned about the possibility that their personal records could be stolen over the internet. If a random sample of 300 college students at a Midwestern university were taken and 228 of them were concerned about the possibility that their personal records could be stolen over the Internet, could you conclude at the 0.025 level of significance that a higher proportion of the university’s college students are concerned about Internet theft than the public at large? Report the p-value for this test. Z0.025 = 1.96
The US Department of Energy reported that 48% of homes were heated by natural gas. A random sample of 336 homes in Oregon found that 142 were heated by natural gas. Test the claim that proportion of homes in Oregon that were heated by natural gas is different than what was reported. Use a 10% significance level. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Based on the hypotheses, compute the following:Test Statistic = p-value =
A Mailing Company sells computers and computer parts by mail. The company claimsthat at least 90% of all orders are mailed within 86 hours after they are received. The qualitycontrol department at the company often takes samples to check if this claim is valid. A recentlytaken sample of 164 orders showed that 135 of them were mailed within 86 hours. Do you thinkthe company’s claim is true? Use a 2.5% significance level.
A political scientist claims that the president’s approval rating in Ogun State is lower than the president’s approval rating in Bayelsa State. To prove his point, he conducted surveys in the two states. Of the 874 individuals polled in Ogun state, 350 favored the president, and of the 1024 individuals polled in Bayelsa state, 438 favored the president. Test the political scientists claim at the 5% level of significance. The p-value of the test is
In a recent year, 73% of first-year college students responding to a national survey identified “being very well-off financially” as an important personal goal. A state university finds that 132 of an SRS of 200 of its first-year students say that this goal is important. Is there good evidence that the proportion of all first-year students at this university who think being very well-off is important differs from the national value, 73%? Carry out a significance test to help answer this question. Construct and Interpret a 95% confidence interval for the proportion of all first-year students at the university who would identify being well-off as an important personal goal. What additional information does the confidence interval provide?
Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6055 patients treated with this drug, 152 developed the adverse reaction of nausea. Use a 0.01 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction?
