Traffic at the airport changed recently, and you collected 36 weeks of data in an effort to estimate the new rate of tire replacements. you found that the average tire replacements per week was 2 and the numbers followed a poisson distribution, but you realize that your sample might not be 100% accurate. what is the 99th percentile of sampling distribution of the mean of tires replaced per week (based on the observed mean of 2 and the sample size of 36)
