The Indian River County Economic Development Board needs to estimate the proportion of all county residents who have earned at least a bachelor's degree. A random sample conducted by the Indian River County Economic Development Board found that 28.7% of all county residents held at least a bachelor's degree. Find three different confidence intervals - one with sample size 387, one with sample size 556, and one with sample size 854. Assume that 28.7% of the county residents in each sample have earned at least a bachelor's degree. Notice how the sample size affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Report all solutions in percent form, rounded to two decimal places, if necessary. When n=387 the margin of error for a 99% confidence interval is given by =When n=387, a 99% confidence interval is given by = When n=556, the margin of error for a 99% confidence interval is given by =When n=556, a 99% confidence…

According to a report on sleep deprivation by the Centers for Disease Control and Prevention, the proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this percent is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents. Suppose we want to calculate a 99% confidence interval for the difference between the proportions of Californians and Oregonians who are sleepdeprived. 1. State the critical value for the interval (3 decimal places): 2. State the difference between the sample proportions, POregon-PCalifornia (3 decimal places): 3. State the standard error of the difference between the proportions (3 decimal places): 4. State the confidence interval being sure to use proper notation (3 decimal places each):
In a study of police gunfire reports during a recent year, it was found that among 540 shots fired by New York City police, 210 hit their targets; among 283 shots fired by Los Angeles police, 77 hit their targets. We want to use a 0.05 significance level to test the claim that New York police have a higher hit rate than the Los Angeles police. Let New York police be represented by p1. Construct a 95% confidence interval and then choose all that apply to this problem. A. Since zero is contained in the confidence interval there appears to be no differnece in the proportions B. New York police have a higer hit proportion than Los Angelos police C. Confidence interval: (-0.0004, 0.1303) D. We fail to reject the null hypothesis E. We should reject the null hypothesis F. Confidence Interval: (0.0396, 0.1729)
