The ages of the 5 officers for a school club are 18, 18, 17, 16, and 15. The median of the ages of the officers is 17.0. The table displays all possible samples of size 2 and the corresponding median for each sample. Using the medians in the table, is the sample median an unbiased estimator? Yes, 50% of the sample medians are 17 or more, and 50% are below. Yes, the mean of the sample medians is 16.8, which is the same as the mean age of the officers. No, the mean of the sample medians is 16.8, which is not the same as the median age of the officers. No, the median of the sample medians is 16.75, which is not the same as the median age of the officers.

2. For the data set below, do a complete boxplot analysis. This includes finding the quartiles, the range, the interquartile range, inner fences, and outer fences. Make sure you draw the graph. Then tell me whether the highest observation is reliable, a mild outlier, or an extreme outlier. 9, 11, 13, 14, 16, 17, 17, 18, 19, 20, 35.

To study how well rats can learn, behavioral scientists used a sample of rats in a maze experiment. Each rat had to find itway through a maze to reach a treat at the end. The rat was timed on its first trial run and again on its tenth eighth trial run. The difference in the times was recorded for each rat. Which of the following is the most appropriate procedure for the scientists to use? A- A matched pair t-interval for a mean diffderence B- A two sample t interval for a difference between means C- a one sample t interval for a sample difference D-A one sample z interval for a population proportion E- A two sample z interval for a difference between proportions
In each situation, find the value of the standardized statistic for the sample mean, and indicate whether the standardized statistic is a t-statistic or a z-statistic. (Round your answer for part (a) to three decimal places.) (a) x = 195, u= 190, s = 21, n = 4 standardized statistic = it's t because s is used instead of o v (b) x = 195,H= 190, o = 25, n = 4 standardized statistic = it's z because o is known (c) x = 168,H= 190, s = 22, n = 25 standardized statistic = : it's t because s is used instead of o
