Answer the fоllоwing questiоns. Justify your аnswer briefly. Which of the following will most likely result in а reduced intervаl width? Decrease the sample size and decrease the confidence level. Increase the sample size and increase the confidence level. Decrease the sample size and increase the confidence level. Increase the sample size and decrease the confidence level. For testing H0 : μ1 - μ2 = 0, Ken obtained a test statistic t = 2.68. If I instead test H0 : μ1 - μ2 = 5 using the same sample, then my t-statistic is Less than 2.68 Equal to 2.68 Greater than 2.68 Not enough information to Answer A student organization at Texas A&M University wants to open a nightclub for students under age 21. There are about 82,000 students on the College Station campus. The organization will move forward if more than 50% of students would patronize the club. If you were hired to design a hypothesis test to support this decision, what should the null and alternative hypotheses be? H0 : μ = 41,000; HA : μ = 41,000 H0 : π = 0.5; HA : π > 0.5 Both a and b are appropriate A 95% confidence interval for the population mean μ is (11.20, 13.64). Using the same data, consider testing H0 : μ = 10 versus HA : μ < 10. The p-value for the test is less than 0.025 between 0.025 and 0.05 between 0.05 and 0.5 greater than 0.5 Not enough information to Answer New pricing deals for GLP-1 weight-loss drugs and aggressive marketing will only go so far if the majority of the public is concerned about side effects or simply not interested. In a recent national survey of 1,225 U.S. adults conducted by Axios–Ipsos (March 6–9, 2026), 221 respondents reported that they are currently using prescription GLP-1 weight-loss drugs or are interested in taking them. In reporting this survey, Axios–Ipsos stated: “About one in five U.S. adults are currently using or interested in using GLP-1 drugs.” Use the survey data to test this claim with a two-sided alternative at α = 0.05. Compute the p-value for the test in Part A. The NORC research institution plans to conduct a similar poll. The researchers want a 99% confidence interval for the population proportion with a margin of error of 0.02. Based on the Axios–Ipsos survey result, how large should the sample size be? Engineers are studying whether cleaning solar panels improves their performance. For each of 55 residential solar systems, the total daily energy output (in kWh) was recorded over a 24-hour period before cleaning and again over a comparable 24-hour period after cleaning, under similar weather conditions. The accompanying JMP output summarizes the analysis of these data. Construct a 99% confidence interval for the mean change in daily energy output after cleaning. Based on the data, is there evidence that cleaning the panels increases the average daily energy output? Give a test at α = 1%. Engineers consider an increase of 2 kWh per day to be practically meaningful. Based on the data, is there evidence that the mean increase exceeds 2 kWh? Give a test at α = 5%. In Part C, what type of error (type I or type II) you may have committed? Explain very briefly.
