- ) For each problem below, Decide whether it describes a confidence interval for a proportion or a confidence interval for a mean. Apply the correct formula to calculate the confidence interval in the format of an estimate + margin of error. During the 2016 season, Mark Williams played in 18 golf matches and used his driver club 126 times, hitting his drives an average of 278 yards per drive, with a standard deviation of 15 yards per drive. Calculate a 95% confidence interval for the distance he was able to hit his driver club in that season.A survey asked, "How many tattoos do you currently have on your body?" Of the 1205 males surveyed, 199 responded that they had at least one tattoo. Of the 1030 females surveyed, 127 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. Let p1 represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 99% confidence interval for p1−p2. The lower bound is nothing. The upper bound is nothing. (Round to three decimal places as needed.)Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p.When 316 third graders are randomly selected and surveyed, it is found that 112 own a cell phone. Find a 99% confidence interval for the true proportion of all third graders who own a cell phone.

(Round your answers to four decimal places.)Sketch the graph.Calculate the error boundSuppose 500 different researchers all randomly select samples of n = 300 individuals from a population. Each researcher uses his or her sample to compute a 95% confidence interval for the proportion who have blue eyes in the population. About how many of the confidence intervals will cover the population proportion? About how many of the intervals will not cover the population proportion? Briefly explain how you determined your answers. About About which is % of the 500 computed intervals, should contain the population proportion. which is % of the 500 computed intervals, should not contain the population proportion.ssume that a sample is used to estimate a population proportion p.
