In Quаrter 1 оf 2025, аbоut 11% оf US employees used AI few times а month in their work. If there is no change in the population behavior, CLT states that any sample proportion will be around the population proportion. In a recent study of 1250 participants who were working in some US company, Gallup found that 185 of them used AI few times a month in their work. The sample proportion of US employees use AI few times a month in their work is [a] Type in decimal form. Do not round. Assuming all CLT conditions hold, use this sample to find 95% confidence interval and conclude: I am 95% confident that the proportion of all US employees use AI few times a month in their work is between [b] and [c] Type or Copy/paste as in StatCrunch output. Do not round. (Rewriting interval in %) I am 95% confident that the proportion of all US employees use AI few times a month in their work is between [l] % and [m] %. Round to whole number percent. Based on your confidence interval, can you confidently claim that the proportion of all US employees who use AI few times a month in their work has increased from Quarter 1, 2025 value of 11%? ( yes / no) [d] Is the sample Gallup collected significant enough to claim that the proportion of US employees who use AI few times a month in their work has increased from Quarter 1, 2025 value of 11%? Test this hypothesis at 5% significance level, Null hypothesis would be [e] Enter decimal number. Alternate hypothesis would be [f] Enter decimal number. The z-stat is [g]. Type or Copy/paste as in StatCrunch output. Do not round. p- value is [h]. Type or Copy/paste as in StatCrunch output. Do not round. The p-value is (less / more) [i] than the level of significance. Conclusion: We (do / do not) [j] have sufficient evidence to reject null hypothesis. Conclusion: [k] (A/ B / C / D) We can confidently claim that the proportion of all US employees who use AI few times a month in their work is now 14.8%. We can confidently claim that the proportion all US employees who use AI few times a month in their work is now 11%. We can confidently claim that the proportion all US employees who use AI few times a month in their work has increased from 11%. We cannot confidently claim that the proportion all US employees who use AI few times a month in their work has increased from 11%
A Brаmptоn pаrcel depоt аudits mislabelled packages. Fоr 10 days it samples 500 packages per day and records the number mislabelled. The daily counts are 18, 25, 20, 15, 22, 19, 28, 21, 17, and 15 (total 200 over 5,000 packages). Use three-sigma (z = 3) limits. Daily mislabelled counts (n = 500 each): 18, 25, 20, 15, 22, 19, 28, 21, 17, 15 (total 200 over 5,000). (a) Select the appropriate control chart for this process, then calculate its centre line and control limits. [OPMG Exam - AI assistance is prohibited.] [6 marks] (b) Is the process in control?
