Please show a detailed step by step procedure. In another pre-election poll, a pollster finds that 372 out of 600 people polled favor Smith. Construct the 95% confidence interval  for the proportion (to nearest 0.001) of people in the whole population who favor Smith.

In a survey of 2554 adults in a recent​ year, 1357 say they have made a New​ Year's resolution.   Construct​ 90% and​ 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals.

You want to determine if the proportion of people who will vote for the president next year has increased due to current events. You take a simple random sample of 1100 individuals and find that 897 of them said that they will be voting in the election. Construct a 95% confidence interval, by hand (mean using the equations in the section). Show your work. And then write the conclusion to the confidence interval (follow the examples in the modules) in a complete sentence.

A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 9% margin of error at a 90% confidence level, what size of sample is needed?

b. In the year 2000, a survey of 1171 U.S. adults were asked who they felt was the greatest President. Of those surveyed, 397 reported that Abraham Lincoln was the greatest President. Use this data to construct a 99% confidence interval for the population proportion of all U.S. adults who would say that Abraham Lincoln was the greatest president before the year 2000. Answer using decimals and round to four decimal places

A Gallup poll of 1487 adults showed that 43% of the respondents have Facebook pages.  Construct a 95% confidence interval for the proportion of adults who have a Facebook page.

In a survey of 2024 adults in a recent​ year, 709 made a New​ Year's resolution to eat healthier.   Construct​ 90% and​ 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals.

In a survey of 2130 adults in a recent​ year, 1491 say they have made a New​ Year's resolution. Construct​ 90% and​ 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals.

Suppose you calculate a 99% confidence interval of 14.71 to 21.64. Determine the margin of error.

In a recent poll 240 people were asked if they like dogs and 75% said they did.  find the margin of error of this pole at the 99% confidence level.
