A survey of 32,782 adults in 2004 indicated that 24.6% of adults were current smokers. A similar study conducted in 1995 of 40,000 adults indicated that 29.7% were current smokers.a. Find and interpret a point estimate of the difference between the proportion of current smokers in 1995, and the proportion of current smokers in 2004.b. A 95% confidence interval for the true difference is (-0.058,-0.045). Interpret.c. What assumptions must you make for the confidence interval i part b to be valid?(…)a. Find a point estimate of the difference between the proportion of current smokers in 1995 and the proportion of current smokers in 2004.(Round to three decimal places as needed.)

A poll reported that only 645 out of a total of 2029 adults in a particular region said they had a "great deal of confidence" or "quite a lot of confidence" in the public school system. This was down 5 percentage points from the previous year. Assume the conditions for using the CLT are met. Find a 95% confidence interval for the proportion that express a great deal of confidence or quite a lot of confidence in the public schools, and interpret this interval. The 95% confidence interval for the proportion that express a great deal of confidence or quite a lot of confidence in the public schools is ____
Do people walk faster in the airport when they are departing or when they are arriving? Researchers measured the walking speed of 45 departing travelers and 71 arriving travelers at Sacramento International Airport. They found that departing travelers had a mean walking speed of 256 ft/min, and arriving travelers had a mean walking speed of 241 ft/min. The standard deviation was 31 ft/min for departing travelers and 58 ft/min for arriving travelers. a. Construct a 89% confidence interval for the difference in mean walking speed between departing and arriving travelers. Round your answers to 3 decimals. Use the smallest of the two degrees of freedom. Critical value: 2* or t* Margin of Error: E = Confidence Interval: [ (Enter the positive one.) ]
One year, the mean age of an inmate on death row was 40.7 years. A sociologist wondered whether the mean age of a death-row inmate has changed since then. She randomly selects 32 death-row inmates and finds that their mean age is 39.6, with a standard deviation of 8.4. Construct a 95% confidence interval about the mean age. What does the interval imply?
