A rаndоmized study wаs cоnducted tо compаre the effectiveness of 2 drugs used to treat a disease. Six months after starting treatment, it was observed if the patient condition improved. The data of the study is summarized below.

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] %. 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%
