In a survey of 2010 adults in a recent year, 713 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. The 90% confidence interval for the population proportion p is (.) . (Round to three decimal places as needed.)

If n=14, (x-bar)=46, and s=18, construct a confidence interval at a 80% confidence level. Assume the data came from a normally distributed population. Give your answers to one decimal place.

A survey asked, "How many tattoos do you currently have on your body?" Of the 1229 males surveyed, 196 responded that they had at least one tattoo. Of the 1015 females surveyed, 135 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. CE Let p, represent the proportion of males with tattoos and p, represent the proportion females with ta Find the 99% confidence interval for p₁ -P₂- The lower bound is 8 The upper bound is (Round to three decimal places as needed.) Interpret the interval OA. There is a 99% probability that the difference of the proportions is in the interval. Conclude that there is insufficient evidence of a significant difference in the proportion of males and females that have at least one tattoo. OB. There is a 99% probability that the difference of the proportions…

Which of the following would result in the narrower confidence interval? a. A sample size of 100 with 95% confidence b. A sample size of 100 with 99% confidence.
