Scientists are studying the sizes of pottery shards found in ancient Roman settlements to determine if there was a shift in pottery styles over time. Below are the diameter values (in units of mm) of pottery shards from the year 200200 A.D. Pottery shard diameters are: {125,140,133,150,160,155,145,132,138,148}\(\left\[\lbrace\)125,140,133,150,160,155,145,132,138,148\(\rbrace\]\right\).. Using 1010 bootstrap samples, construct a 99%99\% confidence interval estimate of the mean pottery shard diameter. The 1010 bootstrap sample means are: 137.6,139.1,139.1,139.2,139.3,139.3,139.6,139.6,139.6,139.6137.6,139.1,139.1,139.2,139.3,139.3,139.6,139.6,139.6,139.6.
