Hello i need help with these statistic questions thank you

question 14:

For the specified margin of error, confidence level, and educated guess for the observed value of the sample proportion, obtain a sample size that will ensure a margin of error of at most the one specified (provided, of course, that the observed value of the sample proportion is further from 0.5 than the educated guess). margin of error = 0.03; confidence level =99%; educated guess = 0.2 Click here to view page 1 of the table of areas under the standard normal curve.

With 95% confidence, the true percentage of all adults in the region who never clothes-shop online is within the bounds of the confidence interval found in the previous step. X B. With 95% confidence, the sample proportion of a survey that asks adults in the region whether they clothes-shop online will be within the bounds of the confidence interval found in the previous step. O C. There is a 95% probability that the true percentage of all adults in the region who never clothes-shop online is within the bounds of the confidence interval found in the previous step. O D. There is a 95% probability that the sample proportion of a survey that asks adults in the region whether they clothes-shop online will be within the bounds of the confidence interval found in the previous step.In a poll, 900 adults in a region were asked about their online vs. in-store clothes shopping. One finding was that 23% of respondents never clothes-shop online. Find and interpret a 95% confidence interval for the proportion of all adults in the region who never clothes-shop online.

The 95% confidence interval is from to (Round to three decimal places as needed.)A researcher in digital culture is interested in statistics concerning the use of social media. A poll found that 29% of a random sample of 2505 Anglophone Canadians who are internet users check their social media feeds every single day. Complete parts a through e below. a) Find the margin of error for this poll if we want 95% confidence in our estimate of the percent of Anglophone Canadian internet users who check social media every day. The margin of error is percentage points. (Round to one decimal place as needed.)b} Explain carefullyr what your interval means. I 99% of the time, the sample proportion of Canadian smartphone users who keep their phones in or beside their bed falls within the confidence interval bounds. 99% of the time, the true proportion of Canadian smartphone users who keep their phones in or beside their bed falls within the confidence interval bounds. There is 99% condence that the proportion of Canadian smartphone users who keep their phones in or beside their bed falls within the confidence interval bounds. There is 99% condence that the sample proportion of Canadian smartphone users who keep their phones in or beside their bed falls within the confidence interval bounds. c] Explain what "99% confidence" means. Hi\" If we were to select repeated samples of 159? Canadian smartphone users, we'd expect about 99% of the condence intervals we created to contain the true proportion of all Canadian smartphone users who keep their phones in or beside their bed. If we were to select repeated samples of 159? individuals. we'd expect about 99% of the confidence intervals we created to contain the true proportion of all individuals who keep their phones in or beside their bed. If we were to select a new sample of Canadian smartphone users. there is a 99% chance that the true proportion of all Canadian smartphone users who keep their phones in or beside their bed will change. If we were to select a new sample of 159?r Canadian smartphone users, 99% of the time the sample proportion of all Canadian smartphone users who keep their phones in or beside their bed will change. Researchers carried out a survey about smartphones. Of 1895 Canadian smartphone users surveyed, 1086 said that at night they keep their phones either in bed or on the nightstand beside their beds. Complete parts a through c below. a) Find a 95% confidence interval for the proportion of all Canadian smartphone users who keep their phones in or beside their beds at night. The 95% confidence interval is (% ) . (Round to one decimal place as needed.)
