A random sample of size n = 225 from a binomial population with unknown parameter p yielded p = .46. a) Is the sample size large enough to use the methods of section 6.5 to construct a confidence interval for p? Explain. b) Construct a 95% confidence interval for p. c) Interpret the 95% confidence interval. d) Determine the minimum sample size required to be 99% confident that the sample proportion driving is within .04 of the population proportion.

2. Construct the 97% confidence interval of the age of adults with at least 3 vaccine shots, assuming that the population standard deviation is 12.
A study regarding the proportion of students who finish their MS degree (graduate) is conducted in two universities (A and B). The results are shown in the following table.
A New York Times article reported that a survey conducted in 2014 included 36,000 adults, with 3.66% of them being regular users of e-cigarettes. Because e-cigarette use is relatively new, there is a need to obtain today's usage rate. How many adults must be surveyed now if a confidence level of 95% and a margin of error of 2 percentage points are wanted? Complete parts (a) through (c) below. a. Assume that nothing is known about the rate of e-cigarette usage among adults. n=enter your response here (Round up to the nearest integer.) b. Use the results from the 2014 survey. n=enter your response here (Round up to the nearest integer.)

A box model is used to calculate a confidence interval in the following scenario: One thousand high school students in a large city are randomly selected for a survey. Among these students, the average reported GPA is 3.0, and the SD is 1.22. For each of the following quantities in the box model, select the answer if the quantity is estimated, not known. Leave the quantities that are known unselected. a. the SD of GPA of high school students in the sample b. the average GPA of high school students in the sample c. the average GPA of all high school students in the city d. the SD of the tickets in the box
A study examined the fat content (in grams) for samples of beef and meat hot dogs. The resulting 94% confidence interval for μMeat−μBeef is (3.2,4.9). Complete parts a) through c) below. a) The endpoints of this confidence interval are positive numbers. What does that indicate? A. The type of hot dog with a higher mean fat content cannot be determined. B. The mean fat contents for each type of hot dog varies greatly from the other. C. The mean fat content is probably higher for beef hot dogs. D. The mean fat content is probably higher for meat hot dogs. Part 2 b) What does the fact that the confidence interval does not contain 0 indicate? A. The difference in the two sample means is significant. B. The difference in the two sample means is insignificant. C. Both samples have a lot of variation. D. There is no difference between the two samples. Part 3 c) If we use this confidence interval to…

4. A sample survey was conducted to estimate the population proportion p that has a certain characteristic. Stratified simple random sampling was used. The results are given below. Stratum Stratum Size Sample Size Pi 1 100 50 0.80 2 60 20 0.70 3 150 75 0.60 4 80 20 0.50 a) b) Find an estimate and a 95% confidence interval for the population proportion p and interpret the meaning of the confidence interval. For a future survey, stratum sample sizes are to be recalulated to estimate p to within 0.1 using an appropriate allocation method. What allocation method would you use if unit costs are given as c₁ = 4, c₂ = 2, c₁ = 5, c = 1? Why? Calculate the stratum sample sizes using the allocation you have chosen.
